The Blue Collar Revival

America’s blue collar workforce divides into four major groups tracked by the BLS, and together they form the physical backbone of the economy. The largest is Transportation and Material Moving — 13,645,620 workers earning a median of $42,740. This is the group that moves everything: 2.07 million heavy truck drivers, 2.98 million laborers and freight handlers, 2.78 million stockers and order fillers, and nearly a million delivery drivers. They are the Amazon warehouse workers, the FedEx drivers, the longshoremen, the forklift operators. Without them, nothing bought online arrives and no store has inventory.

Production Occupations employ 8,743,450 workers at a $45,960 median. These are the people on the factory floor: machinists, assemblers, welders, food processing workers, chemical operators, and quality inspectors. Production employment has barely budged since 2014 (8.93 million then versus 8.74 million now), but wages have surged — a 44.9% increase over the decade, from $31,720 to $45,960. The factory workforce isn’t growing. It’s getting paid more to stay.

Construction and Extraction employs 6,361,720 workers at a $58,360 median — and this group has been on a remarkable growth trajectory. In 2014, it had 5.29 million workers. By 2024, it had added over a million, reaching its highest employment in at least a decade. This is the group building the data centers, apartment complexes, solar farms, highway expansions, and semiconductor fabs that dominate the headlines. The median construction wage has risen 41% since 2014 ($41,380 to $58,360), outpacing the all-occupation increase of 39.3% over the same period.

Finally, Installation, Maintenance, and Repair employs 6,045,020 at a $58,230 median. This is the group that keeps everything working: the HVAC technicians, auto mechanics, industrial machinery repairers, electricians who maintain rather than install, and general maintenance workers. Their median of $58,230 nearly matches construction, and their employment has also grown steadily, from 5.24 million in 2014 to over 6 million today.

Combined, these four groups employ 34,795,810 workers — 22.6% of the total American workforce. Nearly one in four paychecks in the country goes to someone who builds, fixes, produces, or moves physical things. And those paychecks are getting larger.

The headline finding in the data is simple and striking: blue collar wages are growing faster than tech wages. Over the five years from 2019 to 2024, the median wage for Computer and Mathematical Occupations rose from $88,340 to $105,850 — an increase of 19.8%. Over the same period, construction wages rose 23.0%, installation and maintenance rose 24.9%, production rose 27.7%, and transportation rose 31.7%. Even the all-occupation median rose 24.3%, outpacing tech.

This reversal is not a statistical fluke. It reflects two converging forces that have reshaped the blue collar labor market since 2020. The first is the pandemic repricing. When lockdowns hit, the workers who couldn’t work from home — truck drivers, warehouse workers, construction crews, maintenance technicians — were suddenly recognized as “essential.” Wages for stockers and order fillers rose 35.5% in five years, from $27,380 to $37,090. Laborers and freight movers rose 32.0%. Forklift operators rose 28.1%. These were the occupations that kept the economy running while white collar workers retreated to their home offices, and the market has permanently repriced their labor upward.

The second force is the skilled trades shortage. For two decades, American high schools and guidance counselors steered students away from the trades and toward four-year colleges. The result is a generation of retirees leaving construction, maintenance, and manufacturing with far fewer young workers trained to replace them. Employers have responded the only way they can: by raising wages. HVAC technicians went from $48,730 to $59,810 (+22.7%) in five years. Diesel mechanics went from $48,500 to $60,640 (+25.0%). Construction inspectors went from $60,710 to $72,120 (+18.8%). Even machinists, whose total employment has been declining for years due to automation, saw their median rise 26.4% as the remaining workers became more scarce and more valuable.

The tech sector, by contrast, has experienced a different dynamic. The rapid expansion of coding bootcamps, computer science degree programs, and offshore development has increased the supply of entry-level tech workers even as demand continues to grow. Tech wages are still high in absolute terms — $105,850 is more than double the national median — but the growth rate has slowed because supply is catching up to demand. Blue collar workers have no such relief. You can’t learn to wire a building in a 12-week bootcamp, and you can’t outsource plumbing to Bangalore.

Within the blue collar world, the skilled trades tell the most dramatic story. These are the occupations that require years of apprenticeship, licensing, and specialized training — and their combination of rising wages and rising employment contradicts the assumption that “good jobs” require a college degree.

Electricians are the flagship example. In 2014, there were 566,930 electricians earning a median of $51,110. By 2024, employment had risen to 742,580 (+31%) and the median to $62,350 (+22%). But the median understates the ceiling: the 90th percentile electrician earns $106,030. A master electrician running a crew or specializing in industrial or high-voltage work can earn six figures without a college degree, without student debt, and with decades of stable demand ahead. Every new data center, every EV charging station, every solar installation, every home renovation needs an electrician. The infrastructure bill and the green energy transition have locked in demand for years to come.

HVAC technicians have had perhaps the most explosive growth of any trade. Employment surged from 261,390 in 2014 to 396,870 in 2024 — a 51.9% increase. This is not a coincidence. It reflects three simultaneous trends: an aging housing stock that needs new systems, a shift toward heat pumps driven by electrification mandates, and a growing number of commercial buildings investing in advanced climate systems. The median HVAC wage rose from $44,630 to $59,810 over the same period (+34%), and the P90 reaches $91,020. An HVAC business owner in a growing metro can earn well into six figures.

Plumbers and pipefitters (455,940 workers, $62,970 median, P90 of $105,150) and carpenters (697,740 workers, $59,310 median, P90 of $98,370) have followed similar trajectories: steady employment growth and accelerating wages. Welders (424,040 workers, $51,000 median) have seen a 20% wage increase since 2019. Even elevator installers and repairers — a small but elite trade of just 23,340 workers — earn a median of $106,580, with the top 10% reaching $149,250. It is one of the highest-paid blue collar occupations in America, reflecting the years of specialized training required and the safety-critical nature of the work.

The one notable exception is machinists, whose story is one of rising wages alongside falling employment. In 2014, there were 392,700 machinists at a $39,980 median. By 2024, employment had fallen to 298,790 — a 23.9% decline — but the median had risen to $56,150 (+40.5%). This is the classic automation story: CNC machines and robotic systems have replaced many routine machining tasks, eliminating jobs but making the remaining machinists — who now program and oversee the automated equipment — more productive and better paid. Fewer machinists, each doing more valuable work.

Not all blue collar jobs are skilled trades. The largest individual occupations in this workforce are the mass mover roles — jobs that require strength, stamina, and reliability more than specialized training. These are also the jobs most exposed to the pandemic repricing, and their wage gains have been among the most dramatic in the economy.

Laborers and freight handlers are the biggest: 2,982,530 workers earning a $38,940 median. This is the warehouse floor — the people loading trucks, unloading containers, and moving pallets. Their wages rose 32.0% from 2019, from $29,510 to $38,940, a pace that outstripped virtually every white collar occupation. The reason is straightforward: Amazon, Walmart, FedEx, and UPS have been locked in a bidding war for warehouse labor since 2020, and the workers benefited.

Stockers and order fillers — 2,779,530 workers at $37,090 — are a closely related group that has undergone an extraordinary expansion. In 2019, there were 2,135,850 of them. By 2024, the occupation had grown to 2,779,530, a 30.1% increase driven almost entirely by the explosion of e-commerce fulfillment centers. These are the workers who pick items off shelves in Amazon warehouses, fill online grocery orders at Walmart distribution centers, and pack boxes at logistics hubs. Their wage growth of 35.5% reflects both the demand surge and the physically demanding nature of the work.

Heavy truck drivers (2,070,480, $57,440 median) are the third pillar. Trucking has been in a perpetual “driver shortage” for over a decade, and wages have responded accordingly. A truck driver at the 90th percentile earns $78,800 — not far from a first-year software developer in a low-cost metro. The occupation requires a CDL license rather than a degree, pays nearly $20,000 above the national median, and offers immediate employment to anyone willing to accept the lifestyle of long-haul driving. For millions of American workers without college degrees, it remains one of the most accessible paths to a middle-class income.

One of the most common misconceptions about blue collar work is that it has a low earnings ceiling — that these are $40,000–$50,000 jobs with no path to higher wages. The BLS data demolishes this assumption. Multiple blue collar occupations have P90 wages above $100,000, and several have medians approaching or exceeding six figures.

Airline pilots ($226,600 median) and air traffic controllers ($144,580) are the outliers at the top. But the more relevant benchmarks for workers considering the trades are the occupations accessible through apprenticeship rather than flight school: elevator installers ($106,580 median), nuclear power operators ($122,610), power plant operators ($99,670), electrical power-line installers ($92,560), and petroleum refinery operators ($97,540). First-line supervisors in construction earn a median of $78,690 with a P90 of $126,690. Supervisors in maintenance and repair earn $78,300 (P90: $124,280). Move into management from the trades, and six figures is not just reachable — it’s typical.

Even in the core skilled trades, the P90 numbers tell a different story than the medians. An electrician at P90 earns $106,030. A plumber at P90 earns $105,150. A carpenter at P90 earns $98,370. An HVAC technician at P90 earns $91,020. An operating engineer (crane and heavy equipment operator) at P90 earns $100,690. These are workers with experience, union membership, or specializations in commercial and industrial work — but they are not outliers. They are the top fifth of their profession, and they earn more than the median software developer outside the top 25 metros.

The data suggests that the earnings ceiling for blue collar work is far higher than most Americans realize. The trades have always had a path to six figures for those who combine skill, experience, and willingness to do dangerous or demanding work. What has changed is that the floor has risen too: even entry-level construction laborers now earn $34,200 at the 10th percentile, up from roughly $25,000 a decade ago. The entire wage distribution has shifted upward, compressing the gap between blue collar and white collar in ways that challenge the conventional wisdom about which careers “pay well.”
