We need some out-of-the box thinking.
Free up priviate enterprise to develop the massive amounts of oil/natural gas recently discovered to make us energy independent, reduce gas prices, provide jobs, and "lubricate" the private economy.
Use the BILLIONS in Federal Royalties paid by the oil/gas producers to pay current retirees/everyone over say, 50, everything SS promised.
Give everyone under that age, or indeed any age, the option of either opting out of SS, or forgoing SS payments in return for a tax credit equal to what SS "owes" you.
Of course, for the above to work, we would also have to massively reduce Fed Government spending, whacking whole departments, and laying off Fed Workers.
Great Opportunity to become self-reliant again!
