I agree with you. Strict environmental and employment standards in US and EU make no sense if companies can just relocate to China and pollute & abuse people there.

I'm a strong proponent of "fair" trade (not "free" trade) for this reason - I'm OK with production moving elsewhere because salaries are lower, there's more resources and/or better climate for production, but it's completely unacceptable if it's done to skirt local environmental/employment/anti-corruption laws, and should be taxed heavily.

I don't quite understand your criticism of "right wing tariff bashing" though - Trump's the one who's bent on introducing tariffs, whereas past governments (including left-wing Obama) were happy to play along...
