Meh. Interest rates are below inflation meaning eventually we will inflate the debt away. Besides, the deficit matters more than the debt and we could (if we chose to) raise revenue a little to cover the gap. The largest creditor is the Treasury and US bond holders and even so, as long as we are making payments towards the interest in the bonds it doesn't matter much anyway.

As long as the dollar is the reserve currency, we don't need to worry much about the debt in any case.

Further further more, not spending the money to get back on track now will only cost more in the longer run.
