I'd have expected better from Warren Buffett. It's not a zero-sum game, the developed countries running chronic trade surpluses like Germany and Sweden (my home country) are fooling themselves, because the only way they can do that is by putting a brake on domestic consumption by keeping wages low.
Everybody in the EU would be better off if those countries actually let their consumers spend the money that they're hoarding. All of that spending wouldn't go on foreign goods, so it would even benefit their own producers as well. Yet German politicians indoctrinated in stupid frugality (that once had a point, but is completely outdated) continue to scold countries that run trade deficits in order to buy German goods instead of suffocating their economy and making it even worse for everybody, especially Germany.
