I basically trust the process of globalization. "You don't go to war with your trading partners." The main fault I pointed out has to do with a lack of protectionary measures for the sections of society most at risk.
I think this also has relevance to the gentrification debate, though looking into the data it seems like governments continue failing on that front. I wasn't smart enough to come up with an alternative to capitalism when I was 15, I'm not smart enough to come up with an alternative to globalization now.
To drill into a point of my quoted assertion: "You don't go to war without support from your trading partners." A world war is an exceptional case. I meant to point at national conflicts, specifically between equals. I think having to defend your ally is a separate problem.
I'd have thought, at least historically, wars were more likely with trading partners - they're going to be close and, by definition, they have stuff that you want.
