The banks are on their way to failure anyway. Inflation is kept down at a retail level largely due to dirt cheap consumer products made in impoverished, slave-states. And energy prices have been kept low by the cartels.
Debt is at incredibly high levels per GDP (as I understand), and foreign debts payment failures have been covered by large cash infusions from the IMF, world bank etc (US taxpayers mostly), but that is close to being maxed out.
Unsecured debt is failing apace with increasing bankruptcies (both personal and corporate).
At some point, bankruptcies may go nuclear. What happens then?
Yes, by all means. Let's stand the central thesis of capitalism on its head and prop up hopelessly unsound, insolvent banks because, after all, they have a right to succeed and we will be helpless without them.
