"However, a radical, critical look at this issue suggests otherwise."

Yeah, but radical, critical looks are stupid, so who gives a fuck what they "suggest"?

The answer to wage slavery is bargaining power achieved through political action. The auto workers of the 1960's were not wage slaves. They were enterprise participants with a senior claim on the first dollar of revenues. If workers make too little, they are "exploited"; it not, then not. The structure is wholly irrelevant. Only the bargaining power matters, and that's a question of politics, not systems.
