Merely being hedged--even well hedged--may not be a complete protection. Consider what happens in a hyper-inflation (as in Germany & Hungary in the early 1920s). Or consider what happens when spiraling fuel costs in dollars go up much more rapidly than the trucking companies can get the regulatory agencies to up their haulage rates, with the fleets suddenly lot bound!
However the provident citizen prepares, there may be terrible day to day problems, unlike anything Americans have seen since the 1860s. You cannot forever "kick the can," from maintaining a self-destructive "Welfare State," down through the generations.
