The comments are interesting. Rightwingers see the undocumented as marauding hordes, stealing our jobs, and left-wingers see them as victims of corrupt business owners. The rightwing solution is to build fences and throw the immigrants in prison, then deport them, the leftwing solution is to throw the employers in jail and throw some money to Mexico. And, oh yeah, make everyone eat only roots and berries from their backyard organic gardens so there’d be no need for migrant farm workers. Neither solution will work.
Again, my pragmatic proposal should work. Yes, I apologize for some numerical errors. But is important to note that the Cato study showed a positive effect on wages; read the report for the reasoning. And we should entertain the possibility that the migrant-employer relationship is mutually beneficial and legalizing the relationship will reduce exploitation.
