When the US is forced into liquidation down the road, the creditors will not segregate some monies out as 'sacrosanct'. Insolvent is insolvent. Also, intra-government debt is still debt, and all those special T-bills in the SS 'trust fund' have long ago been borrowed against and spent. All the rosy talk is based on economic projections, spending discipline, and a concurrent lack of inflation that will never, ever come to pass.
As bad as Social Security is, Medicare dwarfs it, and the US populace is getting sicker by the year. By 2020, HALF of the US will either be fully diabetic or nearly so.

Good luck with that.
