If the debt maintenance, interest payments, go into default, then the Argentine model kicks in. Explosive inflation coupled with massive economic malaise, radical cutbacks in social programs, spectacular erosion of the middle class, expanded disparity in the distribution of wealth. Also higher taxes and forced privatization of assets to meet obligations, mostly interest rather than principal. The latter is definitely counterproductive, except from the perspective of those getting their payments, and those buying assets at fire sale prices... Our only saving grace, so far, is that our debt is in our own currency, somewhat avoiding the double-whammy of currency devaluation. But in a global economy, it still hits hard. Think $2/gal gas is bad? Try $5. Cheap imported goods? Huh-uh.... Inexpensive food? Not when global purchasers raise demand for cheap american ag products...
Yllus' assertions about the debt are, to be kind, unfounded-

At the end of WW2, the debt was huge, but necessary. Had we lost, debt wouldn't have been an issue, and we ended up as the only industrial power left standing, other than the Soviets, whose mismanagement and ideology doomed their system... so the debt could be rapidly paid off...
As federal debt rises, investment capital is soaked up, too, limiting growth in the private sector...
And of course, let's not mention getting less for every tax dollar as interest costs increase as a % of federal expense. Currently that's ~$330B/yr, 12% of revenues, at historically low rates, the third largest non-SS expense behind the military and all of HHS... A 1% interest bump raises the payments on $7.5T by a mere $75B/yr... forever, under the current scenario...
Looting by the financial elite now via tax breaks for the highest incomes and corporate/military pork, payback by the citizenry later- debt maintenance being the single most important govt expense...
It's part and parcel of the "Starve the Beast" Rightwing scenario of how to get govt "off the backs" of America's wealthy... force an end to virtually all of the "evil" social programs, return to a pre-WW1 wealth distribution scenario... except that they'll now have real leverage in the form of the Debt... They'll try to blame it all on social spending, when it's really by design...
