Social Effects of Globalization
The present problem with Globalization is that it's only halfway implemented. Lets define Globalization inadequately as the free and frequent movement of stuff across national borders. Globalization with respect to Money is going very well. Capital flows move happily across the world, supported by an impressive international framework. Trade is pretty reasonably free. We've got some stupid restrictions on stuff like agriculture and textiles that amount to a big subsidy to agribusiness and a few politically connected industrial barons.
We don't have free movement of people. Not even close to it. And that's the third big piece of the triforce.
Diligent Economic scientists everywhere have chronicled the economic problems this causes. Essentially, you get dislocations of people that benefit some people (lower-class blue collar Americans) and hurt some people (everyone in Mexico).
I'm wondering more if this creates some problematic social issues. Lets say for a moment that social harmony and understanding of other cultures requires some level of actually mixing and hanging out with them. So while the Middle East is getting, say, a big influx of American culture, goods, and money, it's not spending time with any real Americans, excepting some charged interactions in Iraq. Similarly, while the American Northeast is getting a lot of imported goods, Mexican restaurants, and Japanimation, it's not spending time with any of the cultures associated with it. And, anecdotally, it seems like places in America without a large influx of immigrants are more prone to Xenophobia. Whereas the San Franciscos of the world just open more Thai/Ethopian fusion restaurants.
So I'm wondering this: if you get an infusion of foreign ideas, money, and goods without that socializing level of human cultural contact, you'll get rising indignation and hatred of the interlopers.
A good counterexample would be the American Southwest, where there's been a Latino backlash somewhat. But even there, people seem pretty accepting of Latinos, considering how dramatic the immigration has been and how limited the backlash has been. (Largely to the Economic losers from immigration)
