Actually, it's specially true for governments, and some people insist on being completely oblivious to that fact. Contrary to what you might believe, money markets do cut off access to credit to a nation that's over indebted and showing off unbalanced books. If that wasn't the case then no eurozone member would have required emergency loans from the IMF and even the EU and EACH just to cover their immediate expenses.
In addition governmentment who control the nation's currency may resort to ramping up inflation to print out extra cash but that doesn't mean they are getting free cashier or aren't empoverishing the whole nation. These magic money-making policies inflict the exact same damage than austerity has with the exception that it restricts access to imports.
The US is a very particular case as money markets somehow treat US debt as a very special case, one whose massive overspending has no impact on lender's perception.
