Seems I recall a old fable that mentions such a plan.

The Grasshopper and the Ants
Put Social Security, and all public pension systems, on a fully funded basis with privately owned, inheritable investment accounts, and we would solve most of this problem in a generation. I keep trying to tell liberals that if they are really concerned about inequalities of wealth, they should support this. Move all American families into the investor class. Most of them are too programmed to connect the dots. They worship government and they will follow their false god into the sewer.
