I dont think this is the only perspective. Without those outsourced industries, the economies of those countries might be worse off and people might have better air and water but face poverty, umemployment and other crises. It'll be better for the West to bring back jobs no doubt.
Countries that have a significant outsourcing footprint, do you think they do it because they're foolish/greedy? if it is so bad for them? There is a pressure especially in overpopulated nations to create jobs and the local economy is not mature enough to create enough jobs nor value to pay well.
