they may not be forced but they are lied to, takin advantage of and abused. they come here with nothing, so when they get here and don't like it they can't just be like "i wanna go home" they are pretty much hostages. they can keep there mouth shut and go back in and work like a slave and get a very small wage or they can speak up and be turned over to immigration to be imprisoned. Food Inc. the movie does a cool little section on this in the film, if anyone hasn't seen it i highly highly highly recommend watching it.
