The thing with China imo is that part of the reason they’ve been so attractive for manufacturing has been that it’s cheaper there, and the reason that it’s cheaper there has been lower wages and lower safety standards. That’s bad for pretty much everyone except for companies making stuff in China, and consumers getting stuff cheaper than is probably viable with more ethical labor practices (and even then it’s not really much of a benefit to them, because those people need jobs too and so the negative impact there offsets that). It is sadly ironic that a country who’s stated ideology originally claimed to be in the interests of labor (not that it actually was, but they talked that way), has made it’s competitive advantage in the global economy pretty much be being a way around labor protections and unions.

Something I could see being potentially useful, then, would be a tariff policy that was roughly “if you make stuff using labor that’s significantly lower paid than our wages, or with worse safety standards, we raise the price to be around what it would be if it had been made to our labor standards, so that there is no advantage in not keeping things fair for our workforce and yours”. I’ve never really been a fan of things like tariffs, because I know that they mainly just make things more expensive and can reduce pressure to compete by domestic companies, but at the same time, the current system both makes the US dependent on goods made by exploited foreign workers as most people don’t have good enough jobs to afford much better than that which is made cheap by that exploitation, and incentives those foreign countries to keep their people trapped in those conditions and not raise standards, to avoid losing that competitive advantage to another country that does not.
