Socialism in general has a record of failure so blatant that only an intellectual could ignore or evade it. - Thomas Sowell

The history of black workers in the United States illustrates the point. As already noted, from the late nineteenth-century on through the middle of the twentieth century, the labor force participation rate of American blacks was slightly higher than that of American whites. In other words, blacks were just as employable at the wages they received as whites were at their very different wages. The minimum wage law changed that. Before federal minimum wage laws were instituted in the 1930s, the black unemployment rate was slightly lower than the white unemployment rate in 1930. But then followed the Davis-Bacon Act of 1931, the National Industrial Recovery Act of 1933 and the Fair Labor Standards Act of 1938 — all of which imposed government-mandated minimum wages, either on a particular sector or more broadly. The National Labor Relations Act of 1935, which promoted unionization, also tended to price black workers out of jobs, in addition to union rules that kept blacks from jobs by barring them from union membership. The National Industrial Recovery Act raised wage rates in the Southern textile industry by 70 percent in just five months and its impact nationwide was estimated to have cost blacks half a million jobs. While this Act was later declared unconstitutional by the Supreme Court, the Fair Labor Standards Act of 1938 was upheld by the High Court and became the major force establishing a national minimum wage. As already noted, the inflation of the 1940s largely nullified the effect of the Fair Labor Standards Act, until it was amended in 1950 to raise minimum wages to a level that would have some actual effect on current wages. By 1954, black unemployment rates were double those of whites and have continued to be at that level or higher. Those particularly hard hit by the resulting unemployment have been black teenage males. Even though 1949 — the year before a series of minimum wage escalations began — was a recession year, black teenage male unemployment th

When I was an undergraduate studying economics under Professor Arthur Smithies of Harvard, he asked me in class one day what policy I favored on a particular issue of the times. Since I had strong feelings on that issue, I proceeded to answer him with enthusiasm, explaining what beneficial consequences I expected from the policy I advocated.
“And then what will happen?” he asked.
The question caught me off guard. However, as I thought about it, it became clear that the situation I described would lead to other economic consequences, which I then began to consider and to spell out.
“And what will happen after that?” Professor Smithies asked.
As I analyzed how the further economic reactions to the policy would unfold, I began to realize that these reactions would lead to consequences much less desirable than those at the first stage, and I began to waver somewhat.
“And then what will happen?” Smithies persisted.
By now I was beginning to see that the economic reverberations of the policy I advocated were likely to be pretty disastrous — and, in fact, much worse than the initial situation that it was designed to improve.
Simple as this little exercise might seem, it went further than most economic discussions about policies on a wide range of issues. Most thinking stops at stage one.

Many have blamed the gasoline shortages and long lines at filling stations in 1973 on the Arab Oil embargo of that year. However, the shortages and long lines began months before the Arab oil embargo, right after price controls were imposed.
