It's much worse than you think, especially in the area of Medicare.
"...America faces a future of soaring taxes and government spending that will cause poor economic performance. Americans will pay onerous taxes, and future generations will have lower living standards than Americans enjoy today. The longer lawmakers wait to enact the necessary reforms, the more painful those reforms will be."
Beware the so-called "experts" (including Congressional Dems) who call for a gutting or elimination of the Medicare Advantage ("Part C") program.
These people fail to see beyond the immediate dollars and sense of this program, and greedily eye a quick and easy target to use while grandstanding about "children's health insurance" (the misguided and back door socialized medicine plan known as "SCHIP"), while ignoring the unintended consequences of such a move.
