US has some of the highest levels of comparative inequality in the world. There are also areas that have been depopulated and others where basic services cannot keep up with the population (housing for example). but that aside, the US has broad political integration and economic integration and has a single demos. The EU is trying to impose economic integration without political integration (or at least without being honest with the scope of political integration) and that will never work. You can't have freedom of movement of goods, services, capital and labour over unequal economies without seriously compensating for it, both 'sides' of the transactions are damaged. Plus it doesn't have a single demos and I don't see how you can magic one into being. a more apt comparison would be to look at NAFTA. It increased trade, but at great overall cost to both sides.
