Any real concern House Republicans may have for low-wage workers is apparently evaporating in the heat of the midterm elections.
Here's the GOP political calculus, as reported by the New York Times:
Republican moderates used a closed party meeting on Thursday to make their case for a vote, saying it was crucial for helping to dispel the party’s antiworker image. The moderates ran into opposition from conservatives who said the wage proposal could turn off campaign contributors with the elections looming and drive away the party’s business base. But some lawmakers said opponents also recognized the political necessity of giving moderates some political cover, a prospect more appealing than potentially losing their majority in the House.
Perhaps there was a "compassionate conservative" somewhere in the room who thought to mention that a national minimum wage hike is likely to harm low-wage workers, especially young urban workers trying to gain some experience and start on a path to economic independence. But, as far as I can tell, the conclusion was that it is better to be actually anti-worker than to have a false "antiworker image."
If House Republicans wish to get out from behind false perception and stand up for the real interests of workers, they should take a look at this good overview of recent empirical work on the minimum wage by James Sherk at Heritage. And here is Cato adjunct scholar and George Mason economics chair Don Boudreaux on why we should expect government-mandated price floors to harm workers. If the vaunted rightwing messaging machine is so amazing, why can't it do more to explain why reducing opportunities for low-wage workers is not pro-worker?
