No, I'd rather see social security done like the federal TSP (401K) plan is operated. That is, it is invested in part in private securities at a good ROI. Imagine if say, 30 to 40% of social security monies were invested in the stock market, another 30 to 40% in various bonds, and the remainer into government securities.
Just the infusion of that much money into the stock and bond market would result in a huge increase in the US GDP. It would infuse corporations and the like with a mass of new money they would use to increase productivity.
