Productive capacity nuked? Really? http://research.stlouisfed.org/fred2/graph/?s[1][id]=INDPRO
The U.S. retains industrial capacity in high end and military areas, but that isn't going to help average people produce items that are valuable to one another and to people in other places, which is the core way to build wealth. We've masked this fact with debt for the last 30 years, and now it appears that that game is over.
