Is Social Security Sacred?

Most commentators and politicians have been keeping their powder dry regarding changes to Social Security. It seems to me that there are a lot of wet fingers being stuck in the air over the heads of some of the usual suspects. However, whenever someone does speak about changes to Social Security, they are quick to say we have a sacred contract with those Americans who are retired or about to retire and that we shouldn’t make any changes to the terms of their benefits. So I have to ask; why?

If voters have the right to elect politicians who legislate payments that come from those too young to vote, and go to those who elected the politicians; then voters also have the right, when they become old enough to vote, to elect politicians who change the legislation in a way that would reduce or eliminate those payments. There is no sacred contract to protect voters who have given themselves income that is derived from the hard work of a younger generation. Maybe the word sacred just doesn’t mean what I think it means.
