Thomas Sowell Explains Some Basic Economics
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. . . .
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. . . .
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. . . .
The net economic effect of minimum wage laws is to make less skilled, less experienced, or otherwise less desired workers more expensive -- thereby pricing many of them out of jobs. Large disparities in unemployment rates between the young and the mature, the skilled and the unskilled, and between different racial groups have been common consequences of minimum wage laws. . . .
