Having traveled extensively in the CIS since 1989, might I suggest that the Russian pensioners who had their life savings destroyed when the ruble was revalued believed with some merit that they had lost a vested right that was owned as if it were property. (By the way, the Soviets in the 1980's Perisroika, as well as throughout the Soviet rule did have savings and they were able to invest, albiet very limited compared to our standards.) The breach of promise is the same regardless of jurisdiction. The fall of Soviet Russia should be instructive to those who presume that massive and sudden economic and political displacement can not occur in the United States.
