resources. Environmentalists thought that a bad thing - something Americans should feel guilty about. So it is not that simply as issue. Maybe as a nation we should lower our standards so the third world can do better - what is it about third world people that they must live in squalor so we can live in relative luxury (people are often desperate to migrate here, remember that).
Of course a specific person will say "my job is lost for it" but the Chinese guy could say "why should I remain in third world poverty so that some American can keep a nice job?"
Maybe some of it should come at our expense. We are like the 1% in world terms.
