Because Social Security is a hole that’s already been dug. It’s much easier to not dig a whole in the first place than to climb out of a deep one you spent decades digging. To get out of social security the gov would have to come up with a whole lot of money it doesn’t have. I’m not even 50, and already 15% of my gross wages over my lifetime would equal a pretty kitty. Yep, 15%, because my employers’ contribution in my name was money that should have been mine. It was taken from me, so either the contract has to be honored or the money has to be returned. Hell, I’ll be extra nice and not even ask for interest.
You obviously haven’t looked at the ponzi scheme very closely. If you get pennies on the dollar they will be devalued pennies. Get it? Wouldn’t it be better for you (and me; age 48) to take what few productive years we have left and create real wealth that can’t be arbitrarily taken at some future date? I’m just sayin’.
