No more cash payments of SS, starting in say, 25 years. If you are old and need assistance, you can either get help from your family, or you can check in to a nice, government run retirement hell hole. You get a roof over your head (and probably a roommate), 3 squares a day, and a nurse on hand to wipe your chin.
I believe that would provide a decent incentive for people to save for retirement, and would cut costs tremendously. Never mind the details right now, just threaten them with "the home", and see what kind of reform we get.
Close, but this idea can be improved upon.
Instead of a nurse on hand to wipe your chin, save the nurses for medical stuff, then take all the welfare, food-stampers, AFDC, etc. freeloaders and put them to work in these hell holes wiping up chins, behinds, changing depends, moping up spills, etc.
Then, take all the retired congress critters and put them to work in the kitchens.
Works for me!
