If you stick some

If you stick some numbers:

Total national debt = 11 Trillion

@5% APR, Payments = 550 Billion per year

Seems Repayable at present.

But, Past 2011, the pressure of Social security+Medicare will stress the budget.

My guess about likely scenarios:
1. Social security tax rate may be extended over all income
2. Social security & medicare payments may be means tested
3. Capital gains rate may be increased (towards income tax rate)
4. Some sort of customs/excise tax may be placed on imports to placate protectionist interests.
