If you keep increasing retirement age, then Social Security is merely another tax, because very few people will actually live to collect it.
Whent it was introduced, life expectance was 65, people just didn't catch on to the scheme.

If people actually collect, and we do, it would seem SS is a working Ponzi scheme. Reform aims to avoid problems which show up after . . . how many years of people actually collecting?
