That's something as an outsider living here in since around last December I've noticed. Your government is quite broken. But it somehow still works. (Paradox, I know!) For instance, the healthcare bill that was recently passed largely solves the textbook problem of information asymmetry in the health insurance market. It almost didn't pass, but it did. Same seems about the immigration laws - although they are yet to be "fixed". It's a country where, ironically, a "professional news organization" like Fox News exists at the same time with with a "comedy" show like the Colbert Report.
> Unless something major changes, the American focus on consumption will eventually erode our influence around the globe.
That's a quote from the original article. I don't quite see how consumption is wrong. Especially, since from what I see, consumption here in the US is based on the idea of buying things that solve problems. That give people the incentive to invent tools to solve problems. Trust me there are a lot of countries where they don't like to spend money at all (consume). There are everyday problems there that aren't solved because tools invented for them will not be bought. Your quality of life is stagnant if "buy only bare minimum" is the model you want to follow.
