seems to me, that so long as the world has no better alternative than the american dollar to protect their wealth, then it really makes no difference how much debt we incur? how much is too much? 15 gazillion? 20? 100? can anyone answer that question?

and, as for the default issue, I understand the feds have enough revenue coming in from current income sources to cover a short term debt call? if not, then a tax increase on selected competing imports, might be appropriate?

keep it simple and keep it safe...
