He's equating slave labor in China with slavery, which is ... not? idiotic, I imagine. At the outbreak of the US Civil War there were about 4 million slaves living in America. Today there are, according to international estimates, about 3.4 million slaves living and working in China[1].

To claim that it is a non-existent problem or that it isn't severe or that it doesn't merit outrage or to imagine that it is somehow on a different level to the chattel slavery of 19th century America is to turn a blind eye to the truth or to try to finely grade suffering in a way that is dehumanizing.

you do realize that your suggested site clearly states that the modern slavery situation in China is almost the same as Japan/Italy and better than South Korea?

How about you go back to your suggest site and read it carefully?

I've seen an excellent documentary on South Korea's rural slavery problem.. Can you point me to a Chinese one?

People nowadays often don't know that the abolitionist movement in the states saw chattel slavery and wage slavery as not particularly different and wanted to abolish both.
