The minimum wage is a pathetic little thing. First enacted in 1938 at 25 cents per hour, it was largely a sop to the International Ladies Garment Workers Union, one of the very few for whose members, even then, such a pittance might matter. Domestic servants and farmworkers — persons of color, not coincidentally — were excluded. And for most of the 80 years since, the effect of the federal minimum on wages and welfare has been small.
There are two reasons the minimum wage doesn't do much. First, the real value of the minimum is low. That value reached a peak 50 years ago under President Lyndon B. Johnson in 1968, at about $10.50 in today's money. It was then eroded by inflation and political neglect, and is today no higher than it was around 1980.
Second, because the value is so low, few workers are affected. In 2015 the total of workers earning at the minimum or below was just 2.6 million — not even 2 percent of the employed workforce at that time. A very large share of those were young, with half of minimum wage workers being 25 years old or younger, and many of those earned tips in addition to their wages.
And yet, few economic policies have been subjected to such obsessive criticism, in particular by mainstream (which is to say, conservative) economists, as the minimum wage. This is not a matter of practice, but of principle. For, in principle, the minimum wage strikes at the heart of their doctrine, like a wooden stake at the heart of a vampire.
Economists teach that markets reward each worker exactly according to what he or she contributes, not more nor less. Hence the wage that is, is right and just. Further, they say that by meddling in the “labor market,” government can only set a minimum wage that is too high, and employers will not hire those workers. Unemployment is the result of this well-meaning but misguided practice.
As often happens, the facts do not agree. One famous study showed that in fast-food restaurants, a higher minimum wage in two otherwise-identical and nearby labor markets led to more jobs. Why? Because with higher wages, workers quit less frequently, and turnover went down.
But there's more. The Swedes discovered in the 1950s that high wage standards promote productivity, improving the performance of industry, therefore raising living conditions for the whole country. More equal countries have more economic mobility. But they also have less economic stress, less compulsion to seek better jobs, and therefore less internal migration and less unemployment.
The minimum wage is an efficient regulation. It doesn't cost much to oversee. It is simple and it is largely self-enforcing. It is not a burden on the federal budget. And it is a blessing for Social Security, since with higher wages payroll tax collections improve.
A high minimum wage would give a raise, in most cases modest, to about a third of American workers. It would put some pressure on businesses that currently pay less — but by and large, what they lose in labor costs they'd make back in sales to a more prosperous clientele.
So should the minimum be raised? Of course it should. By how much? Enough to matter. Is the Fight for Fifteen asking too much? Not in my opinion. Would Texas be hurt? No. Texas would benefit, because we have in Texas too many low-wage workers, too much poverty, too many people getting food stamps and other welfare because they aren't getting paid enough.
At the deepest level, the minimum wage embodies justice. It speaks to the words of Martin Luther King Jr., that “all labor has dignity” — and so deserves a decent rate of pay. Productivity and pragmatism have nothing to do with this. It is a moral judgment, based on the belief that the community has the final right to set standards, by which all members of the community must abide.
For this reason above all, Happy Birthday, minimum wage.
