I agree that we need to harmonize regulations for trade, but guess what? We're already doing that and the Chinese are responding by getting cleaner so they can compete in more areas. In fact the US is one of the most pollution-heavy developed countries, so if anything the US is exploiting our shared global environment. The reality is that, globally, there is a low skill labour glut because most countries are only now developing advanced education systems. If you want to stop competition from low skill labour you ultimately need high tariffs or extreme mechanization / automation, neither of which are good in the long run for poor people here.
