One of the more insidious effects of minimum wages is that it lowers the cost of racial discrimination; in fact, minimum wage laws are one of the most effective tools in the arsenals of racists everywhere, as demonstrated by just a couple of examples. During South Africa’s apartheid era, its racist unions were the major supporters of minimum wages for blacks. South Africa’s Wage Board said, “The method would be to fix a minimum rate for an occupation or craft so high that no Native would likely be employed.” In the U.S., in the aftermath of a strike by the Brotherhood of Locomotive Firemen, when the arbitration board decreed that blacks and whites were to be paid equal wages, the white unionists expressed their delight saying, “If this course of action is followed by the company and the incentive for employing the Negro thus removed, the strike will not have been in vain.”
