It’s time to embrace minimum wage federalism.

As minimum wage increases take effect in states and cities, there is a bright side for wage-floor skeptics. Not only is Washington, D.C. becoming less relevant in the wage debate, but these real-world policy experiments may help shift the conversation from intentions to results. In fact, people on both sides of the wage issue would benefit from Congress getting out of it altogether. The time has come to abolish the national minimum wage and leave the issue to the states.
