I'm not an economist, a lot of mismanagement and kicking the can down the road is about to unwind. The folks at the top don't seem to realize how thin the veneer of civilization really is. They finally gave in to Roosevelt, and he saved their ass in the 1930s. I doubt this time will prove as lucky.

The standard advice, pay off all debts, have some cash on hand, stock up on food, fuel, toilet paper. Make friends with your neighbors. Have skills that will be in demand, like being able to fix things.
