Forty percent of American workers are salaried. Of the 75.6 million paid by the hour, 1.9 million earn the federal minimum or less, and of these, more than half are under 25 and more than a quarter are between 16 and 19. Many are students or other part-time workers. Sixty percent of those earning the federal minimum or less work in restaurants and bars and are earning tips -- often untaxed, perhaps -- in addition to their wages. Two-thirds of those earning the federal minimum today will, a year from now, have been promoted and be earning 10 percent more. Raising the minimum wage predictably makes work more attractive relative to school for some teenagers, and raises the dropout rate. Two scholars report that in states that allow persons to leave school before 18, a 10 percent increase in the state minimum wage caused teenage school enrollment to drop 2 percent.
The federal minimum wage has not been raised since 1997, so 29 states with 70 percent of the nation's work force have set minimum wages of between $6.15 and $7.93 an hour. Because aging liberals, clinging to the moral clarities of their youth, also have Sixties Nostalgia, they are suspicious of states' rights. But regarding minimum wages, many have become Brandeisians, invoking Justice Louis Brandeis' thought about states being laboratories of democracy.
But wait. Ronald Blackwell, the AFL-CIO's chief economist, tells The New York Times that state minimum wage differences entice companies to shift jobs to lower-wage states. So: states' rights are bad, after all, at least concerning -- let's use liberalism's highest encomium -- diversity of economic policies.
The problem is that demand for almost everything is elastic: When the price of something goes up, demand for it goes down. Obviously were the minimum wage to jump to, say, $15 an hour, that would cause significant unemployment among persons just reaching for the bottom rung of the ladder of upward mobility. But suppose those scholars are correct who say that when the minimum wage is low and is increased slowly -- proposed legislation would take it to $7.25 in three steps -- the negative impact on employment is negligible. Still, because there are large differences among states' costs of living, and the nature of their economies, Sen. Jim DeMint, R-S.C., sensibly suggests that each state should be allowed to set a lower minimum.
But the minimum wage should be the same everywhere: $0. Labor is a commodity; governments make messes when they decree commodities' prices. Washington, which has its hands full delivering the mail and defending the shores, should let the market do well what Washington does poorly. But that is a good idea whose time will never come again.
