You can't just dismiss the demographic argument. The beautiful thing about demographic arguments, unlike just about everything in macroeconomics is it's predictable decades in advance in its magnitude. China really fucked themselves with their one-child policy, there's no way to fix that aside from mass immigration and I don't see that happening, do you? So demographics will eat them in the end. The US have had enough immigration, legal and illegal, that the aging baby-boomers (much milder than what China has to face to begin with) won't be as bad.
