It is different, but there are similarities: the more debt accrued, the more resources that go into servicing that debt; the more debt accrued, the less likely you are to be able to secure additional debt. A US defective of $10T required 6% of the federal budget to service in fiscal year 2011. Currently, accrual of debt is outpacing both inflation, and increases in revenues. This might still be fine _if_ the additional debt has a positive impact on GDP growth, but that's not entirely obvious. Japan has been in a similar situation for two decades. 25% of their national budget is used for servicing loans.
