Large part of the economies in the west gets wasted in meddling in other nation policies, US does that to maintain it's super power. I mean imagine you have neighbors but you keep interest in 2 miles away from your home and use your money to mess with people who live that far. Same with US, it was bound to happen, sooner or later USD would fall down and banks would do too. It's just a matter of time. Final nail in the coffin is importing immigrants from Taliban infested regions of middle east, then US can rest in peace. They did it to themselves!
