There isn’t one.

What should be a great empirical fact is that shortages and a decrepit economy were caused by political factors and blamed on natural factors.  It was the environment.  It was over-population.  It was “malaise.” These things caused the economic crisis and long lines waiting to get some gas.

We were assured this was simply the natural order, that we were using up resources.  And it was all false.  These shortages just sort of vaporized after new political policies were put in place.
