Anyone who chooses to work for free, by their own decision, is being taken advantage of?
Please refer to the definition of the word "coerced".
He's not talking about the unpaid internships that college guys voluntarily apply for to get experience. He's talking about the unpaid "volunteer" work which high school kids are mandated to perform as a precondition to getting their diplomas.
Anyone that chooses to work for free chooses to be a slave. Whether they are a happy slave or not is irrelevant.
I prefer to be the master in those types of situations. IE - I'm happy to take your free labor. (Come to think of it, how could I get the government to require everyone to give me their free labor, hmmm...)
:-P
