The current feel-good push for a $15 an hour minimum wage has nothing to do with helping workers and everything to do with advancing the goals of the left wing, especially the labor movement.
This is true despite the occasionally soaring rhetoric of President Obama amid the Left's incessant whining about "income inequality," itself a particularly un-American concept, an imaginary evil that dwells only in the nightmares of left-wingers. The fact gets lost that the minimum wage itself and continuing increases in the minimum wage hurt working people. Period. And as economist Thomas Sowell has pointed out, minimum wage laws themselves have an inglorious history, having been used to price minorities out of labor markets. If a racist business owner has a choice between a person whose race he likes and someone whose race he doesn't like and their services cost the same, take a guess whom he'll pick.
