The workplace is not involuntary. Most people have to eat, have someplace to sleep and so on. This means that they need to work, unless, of course, you are assuming that the government will cover their necessities out of tax revenues. The workplace is also quite violent. People are forced to work and forced to take the terms offered with the threat of violence, starvation and exposure hanging over their heads. Just because the boss isn’t standing their with a cudgel in hand doesn’t mean that he or she is not violent or not in favor of compulsion.
Your naivete is touching.
