I'll derail this thread and say that SS is a prime example of why government health care will not work. SS looks easy on the surface - take money in, give money out. It's supposed to be autonomous from the rest of the budget and it's supposed to be self sustaining. And look at it. Anyone who thinks that a government run healthcare system, which is orders of magnitude more complex, can work effectively given the gov'ts history with SS, is living in a dream world.
Before anyone calls me a right wing Bush loving Obama hating whatever, I'll caveat by saying that I am not a republican, and my philosophy on government is simple - don't spend money you don't have.
