The federal minimum wage has been $7.25/hour since 2009. Thirty states and many cities have higher minimums, with several (CA, NY, MA, WA) at or near $15-17 and rising. The federal tipped-wage minimum is $2.13/hour for tipped workers in many states.
Proposals like the Raise the Wage Act would phase the federal minimum to $17/hour by 2028 and eliminate the tipped subminimum.
Empirical research on minimum-wage increases is contested. Card-Krueger (1994) and many subsequent studies find modest or no employment effects from moderate increases; Neumark-Wascher and others find more negative effects. There's broader agreement that very large increases relative to local median wages have stronger negative effects.
