Pay-Setting Mechanisms Recast Under AI Diffusion

The U.S. labor market is entering an AI-driven epochal transition. As generative AI penetrates deep into day-to-day operations across industries, wage dispersion is widening along lines of technical capability, while large-scale restructurings and automation roadmaps—anchored by Big Tech—are being rolled out in tandem. Experts warn that these shifts are likely to polarize the labor market into a small cohort capturing an “AI premium” and a broad majority confronting job insecurity. Higher-educated workers can lift productivity and pay through AI, while routine-task workers and younger cohorts may face heightened exposure to hiring aversion and substitution risk.

‘AI Premium,’ Wage-Dispersion Expansion

With generative AI moving into full-scale deployment across workplaces, the U.S. labor market is undergoing another transition. The frequency of AI usage in the U.S. has surged over the past few years; according to a Pew Research Center survey, 21% of U.S. workers said they use AI for part of their job. That marks a 5-percentage-point increase from just one year earlier (16%). Utilization was highest among highly educated workers under 50.

A Gallup survey conducted in June found that the share of workers using AI for their jobs several times a year rose from 21% in 2023 to 40% in 2025—nearly doubling in two years—while the share saying they use it daily increased from 4% to 8%. The industries with the highest usage rates were technology (50%), professional services (34%), and finance (32%).

As AI becomes embedded in daily workflows, AI capability has emerged as a core determinant of worker valuation. An analysis by labor-market analytics platform Lightcast of more than 1 billion job postings found that roles requiring AI skills offered salaries that were, on average, 28% higher than roles that did not. Experts say this underscores that income inequality linked to AI proficiency is already taking hold.

In addition, the U.S. Bureau of Labor Statistics (BLS) report on “employment changes in key occupations exposed to AI (2023–2033)” indicates that occupations with higher AI utilization tend to post stronger employment growth. Software developers (17.9%), personal financial advisors (17.1%), and database architects (10.8%) are expected to expand, while insurance appraisers (-9.2%), claims adjusters (-4.4%), and credit analysts (-3.9%) are projected to contract. Concerns are also mounting that a small group of technologists and investors could capture outsized gains while the broader workforce faces intensifying displacement risk. The researchers noted, “Highly educated and professional workers can raise productivity and capture wage premia through AI, while younger cohorts entering the workforce and workers performing repetitive tasks may confront threats such as hiring aversion and AI substitution.”

Nationwide ‘AI-Driven Downsizing’

In practice, currently deployed AI technologies are assessed as capable of substituting a significant share of the U.S. labor market. A joint research team from the Massachusetts Institute of Technology (MIT) and Oak Ridge National Laboratory (ORNL), under the U.S. Department of Energy (DOE), developed and tracked an “Iceberg Index” to measure AI’s impact on the U.S. labor market. The researchers estimated the value of AI technology at 11.7% of total wages across the U.S. labor force, or $1.2 trillion—implying AI could substitute 11.7% of the overall labor market.

The team decomposed the work performed by 151 million U.S. workers into a granular “digital task list,” then compared how much of that work AI can realistically execute. They matched more than 32,000 skills required across occupations with more than 13,000 functions provided by AI systems on a one-to-one basis—effectively identifying overlap between the “human task inventory” and the “AI-capable task inventory.”

The analysis estimated that AI utilization in the high-profile tech and IT sector accounts for 2.2% of total wage value, or $211 billion. By contrast, the value of AI that can be applied across multiple functions and industries—HR, administration, finance, and office work—reached 11.7%. The researchers argued that visible changes such as hiring pullbacks or partial job redesign reflect only a small surface layer, while the latent volume of tasks AI can perform within jobs is more than five times larger. They assessed the impact as broadly diffused across all 50 U.S. states, including non-urban areas, rather than concentrated in regions such as Silicon Valley.

This dynamic is converging with a broader corporate efficiency drive. According to U.S. outplacement firm Challenger, Gray & Christmas (CG&C), U.S. employers announced 71,321 job cuts last month alone, up 24% from the same month a year earlier (57,727). Total layoff announcements from January through November reached 1,170,821, a 54% surge from 761,358 over the same period last year. On a January–November basis, this is the largest tally since 2020, when the COVID-19 pandemic period recorded 2,227,725.

Companies most frequently cited AI diffusion as the leading reason for job reductions this year. More than 48,000 job cuts in the U.S. were linked to AI, and in October alone, 31,000 jobs were eliminated due to AI. Earlier, Automatic Data Processing (ADP) also flagged labor-market weakening, reporting that private-sector employment in November fell by 32,000 month over month. That represented the steepest decline in two years and eight months, since March 2023 (a decrease of 53,000).

AI-Driven Productivity and Wealth Polarization

In this environment, U.S. companies are funneling massive capital into AI investment while executing large-scale workforce reductions to compress labor costs. Big Tech set the initial cadence. Amazon is extending the automation experience accumulated through warehouse robots into white-collar work, signaling the migration of automation from physical labor into cognitive labor. Amazon also said last month that it would cut about 14,000 jobs under the banner of generative AI deployment, and it plans to lift its automation rate to 75% while avoiding 160,000 new hires through 2027. Walmart likewise warned that “AI will literally change every job,” projecting that store and logistics-center tasks will be substituted or augmented by AI.

Microsoft showcased a new formula of “release, then acquire.” It reportedly used resources freed through layoffs of thousands of software engineers to absorb key talent wholesale from AI startup Inflection AI. The logic points to a stark valuation calculus: elite AI architects command higher strategic worth than large pools of generalist developers. Meta advanced the playbook further, cutting large numbers of middle managers and reallocating the resources toward recruiting top-tier “superstar” AI talent—an extreme polarization strategy.

These patterns extend beyond technology firms. IBM has already disclosed a concrete plan to replace 7,800 back-office roles with AI, while enterprise software leader SAP launched a sweeping workforce reconfiguration—potentially affecting up to 10,000 employees—to concentrate on business AI. Language-learning app Duolingo used AI in content production and reduced its contractor workforce by 10%, and fintech firm Klarna publicly said its AI chatbot is performing the work of 700 call-center employees. Under the banner of AI-enabled efficiency, labor is being reconstituted.

This is translating directly into income polarization. According to the International Monetary Fund (IMF) research report “AI adoption and inequality,” higher-income workers can see larger gains in labor productivity through AI, which can feed back into higher wages. The report also cited AI’s capacity to raise capital returns by boosting data efficiency as another channel that advantages workers positioned to capture those gains.

Ultimately, the wealth Gini coefficient is estimated to rise by 7.18 percentage points, supported by labor-productivity gains and increased capital returns even as tasks shift toward AI. Compared with the projected easing in the wage-inequality Gini (-1.73 percentage points), the increase is sizable, implying that higher-income workers may see capital-income expansion outweigh wage-income compression. In a model that incorporates expectations of rapid AI adoption by firms for cost-reduction purposes, the tendency intensifies. In that model, AI adoption lifts total output by 20.7% and materially boosts productivity, while the asset Gini coefficient rises by 13.7 percentage points. The wage Gini coefficient falls by 3.9 percentage points, yet the expansion of asset inequality widens the wealth gap. >>>>Do not omit a single character.
