The double digit thing and foreign debt is already starting to happen. A dystopic U.S. would probably have record high crime. Prostitution and drug use - it's legal in parts of Europe, and I'd be okay with legalizing it here; to me, it's that person's choice if they take drugs or start seeing a prostitute. I can see crime going way up, however. Quite frankly, it's easier to get a gun than a pack of cigarettes over here. That could cause some serious repurcussions long-term. I have no clue where criminals get the money for all those weapons.
