You know, when I was in college, there was a big debate: Do unions raise wages? Well, with regard to industrial unions, there were arguments back and forth -- international competition. It is now clear, I think, that whether or not you think unions raised wages 50 years ago, the absence of unions and their weakness that is inflicted by anti-union public policy depresses wages. The fact is that people who are not represented, in the service industries in particular, are the victims of policies which depress their wages.
