Ron Paul's plan balances the budget in three years, and does not cut medicare or social security, or veterans benefits or student loans. He has other plans (tax credits and savings accounts where the balance rolls over from year to year) which would introduce care about pricing into the market for people NOT on medicare or medicaid (medicaid is given in block grants to states to design their own programs for states w/o federal overhead) because what people don't use on medical care rolls over in their account so there is incentive to want to keep the price for care down. This would drive down medical costs instead of pumping them higher as govt subsidy does now. Long term it will likely take care of social security forever if he gets his plan through because a balanced budget and his other reforms should pretty much eliminate inflation. Whether long term something like raising the age for medicare is necessary because it doesn't completely fixed won't be known until after Ron's plan is complete, three budget years out from when adopted. Because it will depend on how much the economy rebounds based on the actions he is taking. So that will likely be decided, in any event, in the following presidential term. But Ron's plan will shore up and tide medicare over, at minimum.
Ron Paul's Restore America Plan is on his web page under the 'issues' tab, and the one hour Des Moines Register interview is the most he's discussed this, since he had his concrete plan, although he discussed the concept in this pbs interview as he was still drafting the plan:
