I think there are two extremes.
Globalist, where global trading is good. Because Americans get loads of cheap stuff off the backs of the Chinese, who work themselves out of poverty in the process, benefiting both parties. The hope is if China achieve superpower status, the country will be all nice and democratic and friendly.
Isolationist, where global trading is bad, because you are effectively trading your future security for piles of cheap stuff now, by enabling China to establish itself as a long term global competitor.
So the first is a short term view, and what might be expected as a result of capitalism (which tends to have no long term view and just wants to maximise profit in the short term) whereas the second is a long term position. You can throw environmentalism into the mix as well, which largely comes out on the isolationist side (more expensive less stuff is less bad for the environment, especially since it is not shipped halfway around the world in the process).
The Globalists generally pretend to be politically left wing/liberal but are in fact anything but). I am not sure what the isolationists are. Both sides seem pretty much out for themselves to me but as ever hide under a veneer of social acceptability.
Objective interpretation is difficult, because people still very much seem to want to attach themselves to either being left wing or right wing, while espousing policies that are in fact anything but IMO.
