No one here is a professional writer, historian, or economist, so I just want to make sure I understand your point:

Are you comparing an economic “comparative advantage” (a “term of art”) with institutionalized multi generational chattel slavery?

(I mean, write whatever you want, but I’ll just back off and politely say “I disagree with your analysis.” The Uyghur situation is a sliver of China’s output and while wrong, it’s more of an ethnic cleansing issue not a cost cutting matter. It isn’t a fair example of the overall growth of China.)
