> The average American does not want to buy stuff from slaves, at any price.

This is a pretty bold claim considering the American history.

> There are a lot of vegans.

No there isn't. Only a small fraction of people are vegans. So I'd say that according to your example, most people in world are meat eaters despite the sufferings of animals.

China is winning at manufacturing not because of slavery. The Chinese infrastructure is advancing much faster than that of the US. I'm sorry but Your fringe view is clearly out of touch with the rest of the world.
