I remember saying in the early 80's farmland may stop inflating but will never go down in value. BOOM, it retraced to 1/3 of the high very quickly when it happened and within a few years was up to 2/3rds of the high. Now it is at or above the high again.

Heinlein said much the same thing...
A fake fortuneteller can be tolerated. But an authentic soothsayer should be shot on sight. Cassandra did not get half the kicking around she deserved
