Maybe it is the same as Dennis Miller’s solution: simply don’t pay it back. Problem solved. :)
It’s also the most moral one of the choices available. Default on the debt and let’s deal with the carnage now rather than forcing future generations to deal with it.
It’s more moral than making my children, who never agreed to the expenditure, and who will never benefit from them, debt slaves.
The added benefit is that nobody will lend us money on the future so we will have to live within our means (now that is “sustainability” I can live with!)
