But there's little to no positive connection between who does the hard work and who gets rewarded for it. Nobody in China nor other country is working their ass off to make cheap stuff for developed countries. They're working their asses off to feed themselves and their families. The effort: very high. The value: not so much for them. I get what you're saying, but covering the effort in valor and moral superiority as…
The value: not so much for them. How is a "dramatic reduction in poverty" not of much value? http://filipspagnoli.wordpress.com/stats-on-human-rights/sta...
It is like (to be hyperbolic) living a life of luxury, but on giving the starving man who labours for you a bit of food, suggesting that that is ample reward for his efforts, because of how much value that bit of food has for him. Then, you can top that off by saying that it doesn't matter how much food he produces for you, it isn't of much value because you have so much already.
People reject the labour theory of value, probably correctly in fundamental terms, but the marginal and subjective theories of value both seem to promote (and justify) this kind of structural inequality.
