I assume you are not referring to Marx's technical definition of exploitation, but simply to the unjust drain of resources from one nation to another, or from a nation to a class, if you like. But the context was different. I understood Mark's reference to Chris as aimed at development, not de-development. South Korea, not Ecuador. Now there is little doubt that SK workers are exploited, but neither is there any doubt that they are much better off today than 25 years ago. That's development, not without contradiction, but progress all the same.
Capitalist development in the manner of SK is something to which all underdeveloped nations aspire to, and properly so. It would be preferable for such development to proceed under ecologically- sensitive auspices, but this is the usual ideal, 'third way' which we can dream about and strive for but often fall short of.
My real target is efforts under left pretenses to prevent imperfect development, the result of which is the exploitation to which you refer. Red-green beats red, but red always beats green. If red necessarily precedes green, then greens are a problem for red.
