I'd say America should bring troops back etc etc, but it has to raise taxes on companies. They make massive profits and I don't see the point in letting retailers make so much profit off sweatshops and close to slave labour (like Nike, and Tesco in Britain).
Of course not every company does that, but they still need to be taxed. What difference will it make if someone like Bill Gates looses the extra million dollars when he has billions? IF they have profits even in the low billions, it is still quite a lot (Profits is after payment of employees and manufacturing and etc yes? Correct me if I am wrong).
EDIT: Even after that, I don't think America's (more like "the world's") economic system will advance, and will end up in permenant decline. Consumerism is not sustainable.
