Similar to how the US bailed out the banks. How about the citizens are bailed out. It would boost the economy. Restore faith in the system!
That might be nice, but... how, exactly? By writing off the debts? That's not so nice for those who are owed. A bunch of those are pension funds, for example. If peoples' pensions get wiped out by by all debts being forgiven, they won't be so happy. By the government giving money to people? But where does the government get the money? By taking on debt? Then the government's even more deeply in debt, which means that…
But it's a lot easier to pay off, especially if you prioritize high risk debt to nationalize, so the government has a lower cost of borrowing (especially if the government, instead of paying off distressed debt, instead purchases it at current fair market value, since then the cost will be below the face value; “healthy” debts don't need a correction.)
