Myth: Raising the Minimum Wage Always Causes Mass Unemployment

The foundational challenge to the 'job killer' narrative came from economists David Card and Alan Krueger in their landmark 1994 study. They compared fast-food employment in New Jersey — which raised its minimum wage from $4.25 to $5.05 — against neighboring Pennsylvania, which made no change. Using Pennsylvania as a natural control group, they found that New Jersey's fast-food employment actually grew slightly relative to Pennsylvania after the wage increase. This study, now considered a cornerstone of modern labor economics, directly contradicted the simple supply-and-demand prediction that had dominated economic thinking for decades, and earned Card a Nobel Prize in Economics in 2021.

Economists Arindrajit Dube, T. William Lester, and Michael Reich extended this methodology by comparing pairs of neighboring counties on opposite sides of state borders — where one county had a higher minimum wage than the other. Across hundreds of such county pairs, they found no statistically significant differences in restaurant employment between higher- and lower-minimum-wage counties. This approach is particularly powerful because neighboring counties share the same local economy, consumer base, and business conditions, isolating the effect of the wage law itself. Their research has been replicated repeatedly and holds up across different time periods and regions.

Real-world policy outcomes further undercut doomsday predictions. Seattle's phased increase to a $15 minimum wage — one of the most closely watched policy experiments in U.S. history — was studied intensively by researchers at the University of Washington. While an early working paper raised concerns about hours reductions in limited data, subsequent and more comprehensive analyses found that employment in low-wage sectors grew following the wage increases, and that earnings for low-wage workers rose substantially. Similar outcomes have been observed in other cities and states that adopted $15 minimum wages, with predicted mass layoffs consistently failing to materialize.

The reason standard economic models over-predict job losses is that they assume perfectly competitive labor markets, where workers can freely move between employers and wages are set by pure supply and demand. In reality, many low-wage labor markets exhibit monopsony power — employers have substantial leverage over workers who face limited job options, transportation barriers, and family constraints. When employers have this kind of market power, they can pay workers less than their actual economic contribution. A minimum wage increase in this context does not destroy jobs; it corrects a market imbalance and transfers value from employer profits to worker wages without reducing employment.

The Congressional Budget Office estimated in 2021 that raising the federal minimum wage to $15 would lift approximately 900,000 Americans out of poverty and increase wages for about 17 million workers directly, with broader ripple effects for millions more. The CBO also estimated a potential reduction of about 1.4 million jobs — a real trade-off that serious economists acknowledge — but this represents roughly 0.9 percent of the workforce, not the catastrophic collapse critics predict. Meanwhile, the federal minimum wage has been frozen at $7.25 since July 2009, its longest stretch without an increase since it was established in 1938. Adjusted for inflation, $7.25 today has the purchasing power of roughly $4.81 in 1968 dollars, meaning the federal floor wage buys dramatically less than it did more than half a century ago.
