I'm not suggesting that tariffs are the answer here - especially as enacted - but at the same time, people defending "free trade" (which is anything but given that the movement of labor across borders is very much not free) should be cognizant of what it is exactly they are saying when using cliches such as "comparative advantage".

To answer the broader question, if you believe in markets at all, then demand creates supply, and supply for cheap (and therefore abused) labor is arguably at least in part responsible for economies like China being so shitty to your average worker. If all Western countries would e.g. slap tariffs on goods imported from places with poor labor rights, but they were specifically contingent on that (and not just a list of countries that our Great Leader has a problem with), that would put the pressure on the Chinese government to raise the standards to remain competitive. That would be the kind of tariff I would support, and I don't buy the argument that if we don't allow for such shitty jobs, the alternatives would be even worse - this is exactly the kind of attitude that creates a global race to the bottom that is the major driver for enshittification all around.
