Oklahoma voters recently voted 55%-45% against a three-year doubling of the minimum wage from $7.25 an hour to $15. They were partly motivated by the truth contained in economist Thomas Sowell’s pithy remark that the real minimum wage is zero; employers can fire staff instead of paying them more.Workers who keep their jobs enjoy their increased pay, but higher labor costs kill jobs. The losers get nothing but a harsh lesson in the unsentimental facts of economics. A recent survey from the Employment Policies Institute found that 3 out of every 4 economists thought the Oklahoma wage hike would mean fewer jobs for young people. It’s as if 3 out of every 4 people expected night to follow day.Yet there are some people who don’t accept the repeatedly proven logic of the turning world. Labor unions, for example, support minimum wage hikes and pretend it’s because they’re on the side of the little guy. The real reason is that if the minimum wage goes up, union wages get bumped higher, too. This benefits those people protected by union agreements, but it hurts the rest down at the bottom of the economic heap. Hypocritical Big Labor is like Robin Hood in reverse, stealing from the poor to give to those with plenty. Unions are on the side of the “haves” against the “have-nots.”
