Seriously, go to this website called Sim Sweatshop. While it might be incredibly frustrating to play imagine if this was the reality of your life?!
After you have been frustrated by this game go over to World Vision or to Kiva and join others who’s desire is that the simulation sweatshop is the only kind of sweatshop that exists in the future.

Rob. Speaking of the subject have you checked out Buying Freedom by Kevin Bales. It talks about the economics and ethics of slave redemption. I checked it out on Amazon and it looks expensive. If you have it can I borrow it?!
