Get a clue. Perry was correct - the present retires have SS because current workers pay into the system. As more people retire and draw SS, and as there are fewer current workers paying into the system, then either tax rates go up on the workers, or benefits are reduced to the retirees.
Besides - don't focus on just Perry - recall that the author - Judge Napolitano is DEFENDING Perry's statement - and he spells out a number of reasons - and I didn't see you refute any of those reasons!!
