At least in the US, we've spent the better part of 80 years building a huge amount of wealth and growth on the backs of debt and externalized costs.

Its interesting, in a morbid humor kind of way, to see people realize that these costs always come due.

Globalization allows a huge amount of growth and many benefits you simply can't get with smaller or stronger borders. It also comes with risks, chief among them the risk that any one country loses self sufficiency and competitive advantage.

I do hope that the heaviest cost we (in the US) pay anytime soon is the cost of outsourcing jobs. We don't know how to manufacture anymore, our populace is extremely unhealthy in historical standards, and both political parties are toying with different forms of socialism. There are a lot of bad outcomes that can come where we're heading, we'd get off easy if it stops at outsourcing some of our high paid jobs to cheaper foreign labor.
