The Healthcare Machine

No sector of the American economy employs more professionals than healthcare. The BLS counts 12.7 million workers across two major occupation groups — Healthcare Practitioners and Technical Workers (SOC 29), and Healthcare Support Occupations (SOC 31) — spanning 86 detailed occupations from pediatric surgeons earning a mean of $450,810 to physical therapist aides making $34,520. Together, they account for 8.6% of all US employment, and their combined payroll of $1.14 trillion — $987 billion from practitioners and $156 billion from support — represents the single largest professional wage bill in the country.

To grasp the scale: the healthcare payroll is larger than the entire GDP of Indonesia. It exceeds the combined annual payroll of the Computer and Mathematical Sciences group ($607 billion) and the Legal occupations ($183 billion). Only the Management group ($1.55 trillion), with its 11 million executives and administrators, writes a larger total check. But management is dispersed across every industry; healthcare is concentrated in a single mission — keeping 330 million Americans alive, functional, and insured.

The machine has grown dramatically. In 2019, the BLS counted 10.6 million healthcare workers in these two groups. By 2024, that number reached 12.7 million, an increase of 2.1 million positions in five years — 20 percent growth that outpaced the overall workforce expansion by a wide margin. Some of this reflects the SOC reclassification that shifted certain occupations between groups around 2022, but the underlying trend is unmistakable: America is building its workforce around sickness and age. The Bureau of Labor Statistics projects healthcare as the fastest-growing sector through 2032, driven by an aging Baby Boom generation that will push the 65-and-older population past 80 million by 2030.

But this is not a monolithic workforce. The 86 occupations divide cleanly into two tiers. The practitioner tier — those who diagnose, treat, prescribe, and operate — employs 9.25 million workers with a weighted mean wage of $106,699 and a weighted median of $90,473. The support tier — those who lift patients, draw blood, prepare equipment, and assist — employs 3.46 million workers with a weighted mean of $45,018 and a weighted median of $43,471. The gap between the two tiers is 2.08 times, and it is the defining structural feature of healthcare compensation. A registered nurse and a nursing assistant often work the same twelve-hour shift in the same hospital hallway, responding to the same call lights. One earns $93,600 at the median; the other earns $39,530.

At the center of the healthcare machine stands the registered nurse. There are 3.28 million of them as of May 2024 — more than the entire population of Chicago. They are the single largest detailed healthcare occupation and the third-largest in the entire economy, behind only general and operations managers and fast-food workers. The RN median wage of $93,600 places them comfortably in the upper third of all American workers, 89% above the national median. At the 90th percentile, a registered nurse earns $135,320 — serious money by any standard, and a far cry from the $66,640 median they earned just a decade ago in 2014.

The nursing wage story of the past five years is one of the most dramatic in the American labor market. From 2019 to 2024, the RN median jumped from $73,300 to $93,600 — a gain of $20,300, or 27.7%. Applied across 3.28 million workers, that wage gain alone represents roughly $66.6 billion in additional annual payroll. The pandemic was the catalyst. When Covid-19 swept through American hospitals in 2020 and 2021, travel nurse agencies were offering $5,000 to $10,000 a week for ICU nurses willing to relocate. Permanent staff demanded — and received — raises to stay. Hospitals that hadn’t given meaningful raises in a decade suddenly found themselves in bidding wars with their own employees. The wage floor reset, and it has not come back down.

Below the RN sits a nursing hierarchy that stretches four levels deep. Licensed Practical and Licensed Vocational Nurses (LPNs), who can administer medications and provide basic clinical care but lack the RN’s scope of practice, number 632,430 and earn $62,340 at the median — a 31.3% gain since 2019. Nursing Assistants (CNAs), the workers who do the physical labor of healthcare — bathing, feeding, repositioning, and answering the call light at 3 a.m. — number 1.39 million and earn $39,530. That CNA wage is below the national median of $49,500, which means nearly 1.4 million healthcare workers providing hands-on patient care earn less than the typical American employee. Their 33.3% gain since 2019 sounds impressive until you realize it moved them from $29,660 to $39,530 — still a wage that puts a family of four near the poverty line in most metropolitan areas.

Above the RN, nurse practitioners have emerged as one of the great workforce success stories of the 21st century. There are now 307,390 NPs in the United States, up from 122,050 just a decade ago — a 152% increase that has reshaped primary care delivery. In 2019, there were 200,600 NPs; by 2024, that number had grown 53.2% to 307,390, the fastest employment growth rate of any large healthcare occupation. NPs earn $129,210 at the median, enough to place them in the top 10% of all American earners. The NP expansion reflects both a nationwide physician shortage and a deliberate policy push: 26 states and the District of Columbia now grant NPs full practice authority, allowing them to diagnose, treat, and prescribe independently without physician supervision.

If nursing is the backbone of the healthcare machine, physicians are its apex predators. The BLS counts roughly 315,360 workers in the catch-all “Physicians, All Other” category, plus tens of thousands more in named specialties: 107,950 family medicine physicians, 66,640 internists, 41,890 anesthesiologists, 33,680 emergency medicine physicians, 26,290 radiologists, 24,800 psychiatrists, 24,080 surgeons, and 18,020 cardiologists. For most of these specialties, the BLS cannot report a median or 90th percentile wage because the compensation exceeds the survey’s reporting threshold. When the data literally cannot contain the number, you know you’re looking at the top of the American wage distribution.

What the BLS does report is the mean — the arithmetic average — and even that understates physician earnings because the survey captures base salaries, not total compensation including bonuses, profit-sharing, or call pay. Cardiologists lead with a mean of $432,490. Pediatric surgeons (a tiny specialty of just 1,050 practitioners) average $450,810. General surgeons average $371,280, orthopedic surgeons $365,060, and radiologists $359,820. Even the “lowest-paid” physician specialty with a reported mean — general internal medicine — averages $262,710, placing it in roughly the 98th percentile of all American earners.

The physician compensation story has its own internal drama. Family medicine physicians, who form the backbone of primary care, earned a median of $238,380 in 2024 — substantial money, but roughly half what a cardiologist or surgeon earns. That pay gap between primary care and specialties has been a defining tension in American medicine for decades. It drives medical students away from family practice and toward the procedural specialties — surgery, cardiology, radiology, anesthesiology — where the compensation is dramatically higher. The result is a chronic primary care shortage even as the overall physician workforce grows.

Physician assistants, often discussed alongside NPs as “mid-level providers,” number 155,540 and earn $133,260 at the median — among the highest non-physician wages in healthcare. Their 29.5% employment growth since 2019 mirrors the NP expansion, and their 18.7% wage gain to $133,260 from $112,260 reflects the same underlying demand: there are not enough physicians, especially in primary care and rural areas, and PAs and NPs are filling the gap.

The dashes in the median column tell their own story. For 11 of these 14 physician specialties, the BLS cannot report a median wage because more than half of practitioners earn above the survey’s reporting ceiling. When you see “—” in a federal wage table, it means the government’s statistical machinery has run out of room. The 10th percentile column is equally revealing: even the lowest-paid cardiologist in the bottom 10% earns $119,970 — roughly 2.4 times the national median. The floor of physician compensation is most Americans’ ceiling.

Below the practitioners lies a workforce that is as essential as it is underpaid. Healthcare support occupations — the CNAs, medical assistants, dental assistants, phlebotomists, and others who make clinical care physically possible — number 3.46 million workers with a weighted median wage of $43,471. That figure is $6,029 below the national median of $49,500. Nearly 3.5 million healthcare workers, the people who touch patients most often and most intimately, earn less than the typical American employee.

The numbers are stark. Nursing assistants, 1.39 million strong, earn $39,530 — barely above the 2024 poverty threshold for a family of four in most states. Medical assistants, 793,460 workers who take vitals, manage patient flow, and handle the administrative glue that keeps clinics running, earn $44,200. Dental assistants, 375,430 workers, earn $47,300. Phlebotomists, the 138,880 workers who draw your blood, earn $43,660. Every one of these occupations falls below the national median.

The irony is severe. These are the workers who face the highest rates of workplace injury in healthcare — back injuries from lifting patients, needlestick exposures, verbal and physical abuse from confused or combative patients. A 2023 Bureau of Labor Statistics report found that nursing assistants had the highest rate of musculoskeletal injuries of any occupation in the United States. They also had among the highest rates of days away from work due to injury. The BLS data quantifies the paradox: the most physically demanding healthcare jobs are the least compensated, and the most intellectually demanding (physician specialties) often involve no physical labor at all.

There is, however, a silver lining in the support tier: wages have risen sharply since 2019. Nursing assistants saw a 33.3% increase, from $29,660 to $39,530 — a gain of $9,870 that was driven by pandemic-era staffing crises in nursing homes and long-term care facilities. Medical assistants gained 27.0%, pharmacy technicians 28.0%, and phlebotomists 23.0%. These gains outpaced inflation (cumulative CPI was roughly 22% from 2019 to 2024), meaning most support workers experienced real wage growth for the first time in years. But the absolute dollar amounts remain thin. A 33% raise on $29,660 still leaves you at $39,530 — a wage that is hard to live on in any major metropolitan area.

The healthcare workforce is not just large — it is growing faster than almost any other part of the economy. Between 2019 and 2024, the occupations that grew fastest tell a story about where American medicine is heading. Psychiatric technicians surged 73.7%, from 78,470 to 136,300, reflecting a mental health crisis that exploded during the pandemic and shows no sign of abating. The demand for psychiatric care has outstripped the supply of psychiatrists (whose ranks actually declined 2.9% over the same period), pushing hospitals and treatment facilities to expand their technician workforce instead.

Nurse practitioners grew 53.2%, from 200,600 to 307,390 — a gain of nearly 107,000 positions. This is not just growth; it is a structural transformation of the healthcare delivery model. In 2014, there were 122,050 NPs in the country. A decade later, there are 307,390 — a 152% increase that has made the NP one of the defining new professions of the 21st century. States that grant full practice authority — allowing NPs to operate without physician supervision — have seen the most dramatic growth, as NPs open independent clinics in underserved communities where physicians won’t practice.

General internal medicine physicians grew 49.4%, from 44,610 to 66,640, reversing a long decline in the specialty. Pediatricians grew 44.5%. Anesthesiologists grew 35.1%. Physician assistants grew 29.5%. The pattern is consistent: every clinician category that can fill a gap in the primary care pipeline is growing rapidly, because the gap is enormous. The Association of American Medical Colleges estimated a physician shortage of between 37,800 and 124,000 by 2034, and the workforce data suggests the response has been to grow the non-physician clinician force as fast as possible.

On the other side of the ledger, some healthcare occupations are shrinking. Psychiatric aides fell 36.6%, as institutions shifted to the psychiatric technician model. Medical transcriptionists declined 22.8%, from 55,780 to 43,070, a slow-motion displacement by AI-powered dictation and clinical documentation software. Recreational therapists fell 21.0%. Licensed practical nurses declined 9.3%, as health systems increasingly preferred the RN’s broader scope of practice. Even nursing assistants dipped 2.2% despite massive demand, a reflection of the brutal working conditions and low pay that drive turnover rates above 100% annually in many nursing facilities.

If healthcare employment growth has been impressive, the wage gains have been historic. The pandemic fundamentally repriced healthcare labor. Workers who had accepted modest annual raises of 2–3% for decades suddenly found themselves with leverage they had never possessed: you cannot run a hospital without nurses, and there were not enough nurses. The result was a wage reset that affected virtually every healthcare occupation.

The biggest percentage gainers since 2019 were concentrated in the lowest-paid occupations. Massage therapists saw a 35.3% median wage increase (to $57,950), psychiatric aides 33.7% (to $41,590), nursing assistants 33.3% (to $39,530), and pharmacy aides 32.9% (to $37,000). At the professional level, veterinarians saw one of the largest gains at 31.5% (to $125,510), driven by a pet-ownership boom that strained veterinary capacity nationwide. Licensed practical nurses gained 31.3%, respiratory therapists 31.2%, and veterinary assistants 30.5%.

The registered nurse gain of 27.7% is perhaps the most consequential because of the sheer size of the workforce. A $20,300 raise applied across 3.28 million workers isn’t just a labor statistic — it is a macroeconomic event. That $66.6 billion in additional annual payroll flows into mortgage payments, car purchases, college savings, and consumer spending in every community in America where hospitals operate. Nurse anesthetists, the highest-paid nursing specialty, saw their median jump $48,420 to $223,210 — a 27.7% gain that pushed them past most physician assistant salaries.

Even in absolute dollar terms, the healthcare raises are enormous. Nurse anesthetists gained $48,420. Veterinarians gained $30,050. Registered nurses gained $20,300. Respiratory therapists gained $19,120. Radiologic technologists gained $17,150. These are not cost-of-living adjustments; they are structural repricing events that reflect a fundamental shift in the bargaining power of clinical labor. Hospitals that once relied on mission-driven loyalty — “you don’t become a nurse for the money” — learned during the pandemic that loyalty has a breaking point, and that breaking point is measurable in dollars.

The deepest structural fact about healthcare compensation is not the physician ceiling or the support floor — it is the gap between them. A cardiologist earning a mean of $432,490 makes 10.9 times what a nursing assistant earns at the median ($39,530). That ratio is wider than the gap between a CEO and a janitor in most industries. Within the healthcare support tier, only one occupation — home health and personal care aides — falls below the nursing assistant in the overall BLS rankings, meaning the CNA occupies the second-lowest rung of the entire healthcare wage ladder.

The practitioner tier itself contains enormous variation. The weighted median of $90,473 for all practitioners masks a range from emergency medical technicians at $41,340 (below the national median) to physician specialties that exceed the reporting threshold. Even among non-physician practitioners, the spread is vast: a dentist earns $172,790 at the median while a pharmacy technician — classified as a practitioner, not support — earns $43,460. That four-to-one ratio within the practitioner tier alone exceeds the total wage spread in most other major occupation groups.

The inequality within healthcare occupations, measured by the P90/P10 ratio explored in Episode 5, is surprisingly moderate for most roles. Registered nurses have a P90/P10 ratio of 2.05 ($135,320 vs. $66,030), meaning the highest-paid RN earns about double the lowest-paid. Nursing assistants are even more compressed at 1.60 ($50,140 vs. $31,390). The highest within-occupation inequality belongs to chiropractors (3.35x), healthcare practitioners “all other” (3.42x), and veterinarians (3.03x) — occupations where income depends heavily on whether you work for someone else or own your own practice.

What makes healthcare unusual is not inequality within occupations but inequality between them. The ratio of the highest-paid occupation (cardiologists, mean $432,490) to the lowest-paid large occupation (nursing assistants, median $39,530) is 10.9x. Compare that to the computer and math group, where the highest-to-lowest ratio (research scientists at $140,910 to help desk at $60,340) is just 2.3x. Healthcare has the widest top-to-bottom spread of any major occupation group in the economy because it spans from some of the most highly trained professionals in America to some of the least credentialed. A cardiologist completes four years of college, four years of medical school, three years of internal medicine residency, and three years of cardiology fellowship — 14 years of post-secondary education. A nursing assistant needs a state-approved training program that can be completed in four to twelve weeks.

The healthcare workforce is not just growing — it is reshaping itself. Some occupations are expanding so rapidly that they are redefining what healthcare delivery looks like, while others are contracting toward eventual obsolescence.

The most significant emergence is the nurse practitioner, whose 152% growth over the past decade we explored above. But other growth stories are equally revealing. Psychiatric technicians nearly doubled from 78,470 to 136,300 (+73.7%), reflecting the explosion of behavioral health demand in post-pandemic America. The National Institute of Mental Health reported that 22.8% of American adults experienced mental illness in 2021, up from 18.9% in 2017, and the treatment infrastructure has expanded to match — but with technicians, not psychiatrists. The number of psychiatrists actually fell 2.9% over the same period, from 25,530 to 24,800, a decline that illustrates a core healthcare dynamic: when the expensive specialists can’t scale, the system scales the cheaper alternatives.

The most telling contraction is the medical transcriptionist, down 22.8% from 55,780 to 43,070. This occupation — once a staple of hospital back offices — is being systematically replaced by AI-powered speech recognition and clinical documentation tools. Companies like Nuance (acquired by Microsoft in 2022 for $19.7 billion) and Abridge have developed ambient listening technology that converts physician-patient conversations directly into clinical notes. The medical transcriptionist is the healthcare equivalent of the computer programmer we profiled in Episode 7: a skilled role that technology is making redundant in real time.

Licensed practical nurses present a different kind of decline — not obsolescence, but strategic replacement. LPN employment fell 9.3%, from 697,510 to 632,430, even as total healthcare employment surged. The reason is scope of practice: many hospitals and health systems have concluded that they would rather employ one RN than one LPN plus supervision, because the RN can perform a wider range of tasks independently. States like California have gone further, implementing minimum RN-to-patient staffing ratios that effectively reduce demand for LPNs in acute care settings. The LPN is not vanishing from healthcare — they remain critical in long-term care and home health — but their share of the hospital workforce is shrinking as the industry standardizes around the BSN-prepared registered nurse.

Even the nursing assistant workforce, despite enormous demand, declined 2.2% from 1.42 million to 1.39 million. This is not a demand problem — nursing homes across the country report chronic CNA shortages. It is a supply problem. When you can earn $44,200 as a medical assistant in an air-conditioned clinic, the proposition of earning $39,530 to lift patients and clean bedpans in a nursing home loses its appeal. The CNA shortage has become so acute that the Centers for Medicare and Medicaid Services proposed minimum staffing standards in 2023, effectively acknowledging that market wages have failed to attract enough workers to this essential occupation.

Healthcare’s $1.14 trillion payroll is not distributed evenly. The practitioner tier at $987 billion accounts for 86.4% of the total, while the support tier at $156 billion accounts for just 13.6% — despite support workers comprising 27.2% of the healthcare workforce. The payroll concentration is extreme: registered nurses alone, at roughly $323 billion in annual wages (3.28 million workers times $98,430 mean), account for 28.3% of all healthcare payroll. Add in nurse practitioners ($40.6 billion), pharmacists ($45.1 billion), and physician assistants ($21.3 billion), and the top four non-physician occupations combine for $430 billion — more than the entire support tier by a factor of nearly three.

Among all major occupation groups in the economy, healthcare practitioners rank second in total payroll at $987 billion, behind only management at $1.55 trillion. When you add the support tier, healthcare’s combined $1.14 trillion exceeds business and financial operations ($925 billion), office and administrative support ($914 billion), and sales ($722 billion). The American economy spends more on healthcare wages than on the combined wages of everyone who builds, maintains, and repairs its physical infrastructure (construction plus installation, maintenance, and repair together total about $800 billion).

The physician payroll, while enormous per capita, is concentrated in a relatively small workforce. If we estimate conservatively that the 315,360 “Physicians, All Other” plus the named specialties (about 700,000 physicians total) earn an average of $280,000 — a rough approximation given the range of means from $253,000 to $450,000 — the total physician payroll is approximately $196 billion. That is 17% of the practitioner total, generated by about 7.6% of the practitioner workforce. Physicians generate payroll at 2.5 times the per-capita rate of the practitioner group as a whole.

Perhaps the most sobering finding in the healthcare data is how many workers in this $1.14 trillion sector earn less than the typical American. The national median wage in 2024 was $49,500. Among healthcare occupations, 24 occupations employing 4.75 million workers fall below that line. That is 37.4% of the entire healthcare workforce — more than one in three healthcare workers — earning below the national median while performing work that is physically demanding, emotionally draining, and medically essential.

The largest below-median occupation is nursing assistants at 1.39 million workers and $39,530. Next comes medical assistants at 793,460 workers and $44,200, followed by pharmacy technicians at 487,920 and $43,460, dental assistants at 375,430 and $47,300, and emergency medical technicians at 177,980 and $41,340. These five occupations alone account for 3.22 million workers — more than a quarter of the entire healthcare workforce — all earning below the median American wage.

The presence of EMTs on this list is particularly striking. Emergency medical technicians — the people who arrive in the ambulance when you call 911, who perform CPR, who stabilize car accident victims on the highway, who deliver babies in the back of a rig — earn $41,340 at the median. That is 16.5% below the national median, less than what a typical office clerk earns, and roughly what a retail salesperson makes at the 75th percentile. Paramedics, the more advanced version of the EMT, earn somewhat more at $50,150, but even they barely clear the national median. The wage of emergency response has been one of the persistent anomalies of American labor markets: we treat the work as heroic and compensate it as clerical.

The below-median healthcare workforce is also disproportionately female and disproportionately non-white. While the OEWS data does not include demographic breakdowns, the Bureau of Labor Statistics’ Current Population Survey shows that nursing assistants are 88% female and 38% Black — the highest Black share of any large occupation in the healthcare sector. Medical assistants are 90% female. Dental assistants are 96% female. The healthcare wage ladder is, in practice, a reflection of historical gender and race dynamics: the occupations that were historically filled by women of color remain the lowest-paid, while the physician specialties that were historically the province of white men remain the highest-paid. The gap has narrowed — the gender and racial composition of medical schools has shifted dramatically — but the wage hierarchy built on those foundations persists.

The healthcare data reveals several patterns that distinguish this sector from every other part of the American labor market. First, the credentialing ladder is steeper and more rigidly enforced than in any other industry. You cannot practice as a registered nurse without a state license, and most states now require a bachelor’s degree in nursing. You cannot practice as a pharmacist without a Doctor of Pharmacy (PharmD) degree — a six-year program that did not become the mandatory entry credential until 2004. You cannot practice as a physical therapist without a Doctor of Physical Therapy (DPT) degree, a requirement that was phased in between 2015 and 2020. Each elevation of the credential bar raises the floor wage for the occupation while simultaneously restricting supply.

Second, healthcare occupations show a remarkably strong correlation between licensing requirements and compensation. Occupations requiring doctoral degrees (physicians, pharmacists, dentists, optometrists) cluster above $130,000 in median wage. Occupations requiring master’s degrees or advanced certification (NPs, PAs, CRNAs, speech pathologists) cluster between $95,000 and $135,000. Occupations requiring bachelor’s degrees (RNs, most therapists) cluster between $80,000 and $100,000. Occupations requiring associate degrees or certificates (LPNs, radiologic technologists, dental hygienists) range from $62,000 to $94,000. And occupations requiring only brief training programs (CNAs, medical assistants, phlebotomists) fall below $50,000. The ladder is remarkably consistent: each additional year of required education adds roughly $7,000 to $10,000 in annual median wage.

Third, healthcare is the sector where the pandemic had the most lasting effect on compensation. The wage gains documented in this episode — 27.7% for RNs, 33.3% for CNAs, 31.3% for LPNs — are among the largest five-year gains for any major occupation in the OEWS data. Most of these gains were concentrated in 2020–2022, the height of the staffing crisis, and they have largely held through 2024. Hospital systems that raised wages have not subsequently cut them, in part because doing so would trigger immediate attrition and in part because many of the raises were formalized through union contracts (nursing unionization accelerated sharply during the pandemic, with major organizing victories at hospitals from Stanford to Robert Wood Johnson).

Finally, the healthcare data underscores a demographic reality that will shape the American economy for decades: the healthcare workforce must continue to grow faster than the overall labor force because the population it serves is aging. When the youngest Baby Boomers turn 65 in 2029, the 65+ population will exceed 80 million — double what it was in 2000. Per-capita healthcare spending for Americans over 65 is roughly three times the rate for those under 65. The math is straightforward: more elderly patients require more nurses, more aides, more therapists, more physicians, more technicians, more of everything. The 12.7 million healthcare workers of 2024 may be 15 million or more by 2034. The healthcare machine does not have an off switch.
