> The eternal problem is that exporting is giving away the output of your people in return for a shiny bauble

That's an important point!

In the case of China, I'd guess that it was a strategic decision to do so. Being in debt with others gives others political power over you - at least as long as you are not stronger (ultimately, in a physical sense) than them. I guess China wanted to avoid that as long as it wasn't strong enough. Now that China is getting stronger and stronger, they are starting to invest that accumulated capital in order to gain political power over other, weaker nations. That's btw. a hot topic even on Germany, if it's ok to let the Chinese buy local companies and other assets.

In the case of Germany, I don't really understand why it went that way. The surplus seems to have become some kind of fetish. During the Greek crisis, the risks of such imbalances became visible. The big risk for Germany is imo that a major country like France or Italy will tip over politically, leading to the destruction of the Euro. There's no playbook for how to handle that and I guess it would be a messy and ugly political process which may render quite some of those collected "shiny baubles" worthless. With European history in mind, I don't think taking that risk is worth it.
