You don't have to like unions to admit they benefited workers. In fact, the money spent on the destruction of unions points to it - why bother if they didn't help workers?

The post-WWII bargain, where productivity growth was split, is gone and not coming back. Whether there's a way to give workers a voice again or not is an interesting question.

Of course, if the class differential gets too big, there's always the pitchfork and torch route, which I don't think anyone (OK, most sane people) wants.
