AI could lift low-skill lifetime pay 15 to 45%
Daily Briefing | July 20, 2026
Most research on AI and work sorts tasks into two bins: the ones machines take over, and the ones machines make people faster at. A new working paper from Stanford economist Lukas Althoff and Hugo Reichardt of the Barcelona School of Economics adds a third bin, simplification, and the addition changes who the winners are. When AI lowers the skill a task requires, the worker who gains most is the one who could not perform that task yesterday. Althoff and Reichardt estimate lower-skilled workers stand to earn 15 to 45 percent more over a lifetime than they would without AI, and they expect the gap between the highest and lowest earners to narrow.
By the Numbers
15 to 45 percent: estimated lifetime earnings gain for lower-skilled U.S. workers under AI, relative to a world without it, per Althoff and Reichardt
Three: categories of technological change in the paper’s framework, automation, augmentation, and simplification, the last of which the authors introduce
Seven: degree fields the paper expects to hold up better in the AI labor market, including mechanics, engineering, architecture, transportation, and physics
Six: fields it expects to fare worse, including political science, sociology, philosophy, law, and religion
Reskilling and Education
Stanford economists make the case that AI narrows the wage gap
Lukas Althoff, an assistant professor of economics at Stanford and a faculty fellow at the Stanford Institute for Economic Policy Research, built a framework with Hugo Reichardt of the Barcelona School of Economics that translates AI exposure scores into wage and employment outcomes for individual workers. Their argument turns on simplification. Automation removes a task from a person, augmentation makes a person faster at it, and simplification lowers the skill floor so that more people can do it at all. Lower the floor on a well-paid task and the workers who move up are the ones previously locked out.
The model produces a set of uncomfortable second-order results alongside the optimistic headline. If AI keeps lowering skill floors, the market price of advanced skill falls, and fewer people find a graduate degree worth its cost. Althoff and Reichardt expect degrees intensive in manual and technical skill, among them mechanics, engineering, culinary arts, cosmetology, architecture, transportation, and physics, to hold their value better than degrees built on verbal and social skill, among them political science, sociology, philosophy, law, religion, and women’s studies. They also find lower-skilled workers have been slower to pick up AI tools, though not slowly enough to cancel out the equalizing effect.

Why it matters: Nearly every workforce plan written in the last two years assumes AI raises the skill bar and that the job is to push people up it. Althoff and Reichardt describe the bar coming down, which puts the return on internal mobility above the return on credential-stacking. Test the assumption directly: pick three well-paid roles in your organization and ask which parts of them AI has already made learnable by the people one rung below.
What Workforce Leaders Are Watching
Which roles in your organization have quietly become learnable by the tier below them, and does your job architecture let anyone actually move into them without a new degree?
If the market value of advanced credentials falls, what happens to tuition reimbursement budgets, and what do you fund instead?
Althoff finds lower-skilled workers adopting AI more slowly. Who inside your company is furthest from the tools, and what is the actual barrier, access, training time, or manager permission?
