It will probably be ugly and I'm not convinced there is a next-thing that will pull America out. Demographics look bad, we've nuked or productive capacity and the culture has rapidly decayed in the last twenty years. There is graft and fraud well marbled throughout the entire corporate and government superstructure.
I realize I'm a paranoid nut job, but I think Gold, Guns and Startups is the right straddle: Gold and Guns for the obvious reasons, Startups because, hey, things could work out (they usually do) and because owning common stock or bonds puts you too far away from the value creation, introducing those troublesome layers of graft and fraud.
