In 1948, white teenage unemployment in the U.S. was 10.2%, while black teenage unemployment was only 9.4%. This was when the effective minimum wage rate was much lower. Today, in a much less discriminatory epoch, but where teenagers are “protected” by a more stringent minimum wage law, white youth unemployment is 13.9%, while black youth unemployment is an astounding and shameful 33.5%. —Walter Block, The Case for Discrimination, 2010
