The world is becoming increasingly global. As economically marginal countries move to becoming service based economies, won't the number of debt slaves decrease? As nations move to become greater consumers won't sweat shops and the like become less a less popular form of labor with "conscientious" consumer nations? (take a look at Nike practices in Asia)

I think as the free flow of products and the development of marginal nations progresses. Your debt slaves will become increasingly endangered.

Do you think that there are still slaves of sorts in the U.S. or other developed nations? If so, who are they?
