Does the minimum wage need to keep up with the cost of living?
Pro-increase sources (NELP, VCU RISE, EPI) say raising and indexing the minimum wage reduces poverty, while the arizona.edu opinion piece and business groups say minimum wages cause a price-wage spiral and job losses.
This question sits at the intersection of policy debate and economic fact, so let me lay out both the empirical situation and the arguments on each side.
The factual backdrop
The U.S. federal minimum wage has not been indexed to inflation. Federal minimum wage remains $7.25 per hour since 2009, losing 30% of its purchasing power to inflation. Unlike the minimum wage in many states, the federal minimum wage is not indexed to inflation, meaning it doesn't automatically adjust each year to account for changes in the cost of living. Changes require congressional action — for the federal minimum wage to increase, Congress must act to send legislation to the president to sign into law.
By contrast, many states have taken a different approach: Twenty states plus the District of Columbia have adopted laws to index their minimum wages to rise automatically with the cost of living, with thirteen states plus D.C. currently indexing increases each year. Historically, purchasing power has fluctuated a lot — the value of the federal minimum wage has fallen sharply over the past 57 years; in 1968, when its purchasing power was at its peak, the federal minimum wage was $1.60 per hour, which translates to approximately $14.91 in 2025 dollars.
The case for tying it to cost of living
The case against automatic cost-of-living increases
Bottom line
There's no single "correct" answer — it's a value-laden policy question, not a settled fact. But the empirical trend is clear: places that don't index to inflation see the real value of their minimum wage erode over time, while indexed jurisdictions maintain purchasing power automatically. Whether that erosion is a problem worth fixing through automatic cost-of-living adjustments (versus periodic legislative increases, or no minimum wage increases at all) depends on how you weigh worker purchasing power against potential effects on hiring, small businesses, and prices — which is exactly why this remains a live and contested political issue rather than a resolved empirical question.
