Interesting tidbit: People in china tend to be happier than people in america. Probably due to the fact that their situation is continuously improving (and communal culture instead of individualist means the whole authoritarian corrupt government thing isn't quite as upsetting or burdensome), whereas that's not true for america.
Sidenote: There's reasons and means to oppose globalisation/globalism other than those, and to desire a domestic manufacturing base. Further, there's really only so many high-tech jobs available. And the more people who go into the, the worse those jobs will be for the people in them, barring some seriously drastic shifts in either corporate mindset (to 'treat your workers well and they'll do well', which is in fact accurate) or policy (which could cause them to pull out, aka they can hold countries hostage for economic benefits). There's the whole worry that rather than enable everyone to have enough and not have to work all the time in order to eat, that automation will instead leave all the wealth in the hands of the few who can work it/own it, while they have no need for the poor, and therefore leave them to rot.
Plus, in some cases, local manufacturing is better for the environment. Significantly better, sometimes, depending on where it's shipped from and their rules about how okay it is to fuck over the environment. There's ways for most everyone to win here. People just don't look at them because they're distasteful in other ways (tariffs, for example; everyone seems to hate the idea of tariffs and any reduction in trade whatsoever, because it would hurt quarterly GDP growth. But I think a progressive tariff, based on how many labor, safety, health, and environmental standards are
not met or enforced compared to the U.S. would help a lot in several ways. And if they levy a tariff back on us, so be it. I've seen it a few times now that no nation has successfully industrialized without hefty protective tariffs. We'll still have trade with other highly developed countries, too, and it helps make up for the difference in labor price in terms of allowing our manufacturers to compete with foreign ones. World peace through free trade sounds great, and mostly works, but I doubt China would start a shooting war over it.
If you're worried about prices rising for the poor, the solution is the same as ever: tax the rich, use it to help the poor. Wealth gap is growing, income gap is growing, and taxes on the wealthy are still very low. I would personally make a new tax bracket where, past 1 million dollars, ~80% of your income is taxed(still not the highest we've had though to be fair we're not in wartime). We've had upwards of 70% taxes on the upper class for several decades after WWI. It was cut by Reagan, and never went back that high again. Wealth gap and percentage of Americans in poverty has increased since, rather than decreasing as it was previously.
@UrbanGiraffe: Comparative advantage based on a lower regulatory burden is a shell of an advantage, not one based in resources or ability. Although you're right that a sudden shift would be bad for just about everyone. Gradual increases, though, that's not gonna have the same shock effect. But again, no country has successfully industrialized without a tax base, and if we've done alright previously without China to make all our shit, we would be able to do it again, given time.
