Many people are blaming the riots in France on the high unemployment rate among young Muslim men living in the ghettoes around Paris and elsewhere. Some are blaming both the unemployment and the ghettoization on discrimination by the French.
Plausible as these explanations may sound, they ignore economics, among other things.
Let us go back a few generations in the United States. We need not speculate about racial discrimination because it was openly spelled out in laws in the Southern states, where most blacks lived, and was not unknown in the North.
Yet in the late 1940s, the unemployment rate among young black men was not only far lower than it is today but was not very different from unemployment rates among young whites the same ages. Every census from 1890 through 1930 showed labor force participation rates for blacks to be as high as, or higher than, labor force participation rates among whites.
Why are things so different today in the United States -- and so different among Muslim young men in France? That is where economics comes in.
People who are less in demand -- whether because of inexperience, lower skills, or race -- are just as employable at lower pay rates as people who are in high demand are at higher pay rates. That is why blacks were just as able to find jobs as whites were, prior to the decade of the 1930s and why a serious gap in unemployment between black teenagers and white teenagers opened up only after 1950.
Prior to the decade of the 1930s, the wages of inexperienced and unskilled labor were determined by supply and demand. There was no federal minimum wage law and labor unions did not usually organize inexperienced and unskilled workers. That is why such workers were able to find jobs, just like everyone else, even when these were black workers in an era of open discrimination.
The first federal minimum wage law, the Davis-Bacon Act of 1931, was passed in part explicitly to prevent black construction workers from "taking jobs" from white construction workers by working for lower wages. It was not meant to protect black workers from "exploitation" but to protect white workers from competition.
Even aside from a racial context, minimum wage laws in countries around the world protect higher-paid workers from the competition of lower paid workers.
Often the higher-paid workers are older, more experienced, more skilled or more unionized. But many goods and services can be produced with either many lower skilled workers or fewer higher skilled workers, as well as with more capital and less labor or vice-versa. Employers' choices depend on the relative costs.
