There was a degree of interventionism in American foreign policy, the notion that we must be the superpower and we have to intervene everywhere, that I think makes no sense.
A leader can`t move a country that`s not ready. You can`t make the waves, but when you see them coming, you can help direct them.
Excessive partisanship is the problem. There has never been a democracy in the history of the world in a polity of any size where you didn't have political parties. Even sometimes over the objections of the people who started it.
Trying to avert foreclosures, once you can't just force the banks to do it as a condition of getting aid, means that you have to put some public money into it or you have to do other things that are politically unpopular. From the macroeconomic standpoint there is overwhelming need to help people reduce what they owe so that we don't get the foreclosures and we don't get people kicked out of their homes. On the other hand, there is great resistance politically to helping people, not all of whom would be worth recipients of the help.
The people who started the American government, the founders of the Constitution, didn't like political parties but they were forced to start them. Nobody ever created political parties in England, they evolved. And there do tend to be two general tendencies that focus around how much government you think you need.
