Remember that taking away bad jobs does not save anyone, quite the contrary. People go from having shit jobs to no jobs, or even worse jobs with lower-profile companies.
Helping them requires creating vast numbers of better paying jobs with better working condition in their country, which require redirecting vast amounts of money to those countries. E.g., by buying even more stuff from those regions, but from manufacturers paying better wages (and selling goods more expensively), so they end up having to massively expand and hire more.
