It is the greatest demographic tsunami in the history of the United States, and we are woefully unprepared for it.  We have made financial promises to the Baby Boomers worth tens of trillions of dollars that we simply are not going to be able to keep.  Even if we didn't have all of the other massive economic problems that we are currently dealing with, this retirement crisis would be enough to destroy our economy all by itself.  During the first half of this century, the number of senior citizens in the United States is being projected to more than double.  As a nation, we are already drowning in debt.  So where in the world are we going to get the money to take care of all of these elderly people?
