Bankers gambled our money away on dodgy bonds and appealed to governments for money to cover the debts they irresponsibly accumulated. Governments say they cannot let banks go to the wall, as they ought to according to the principles of capitalism, so they agreed to underwrite them. Trillions of dollars were passed over to the banks. Now national treasuries were empty or also in hock, so governments say they have to borrow money from the banks to run the economy, and have to cut public expenditure on education, health and so on, and increase public taxes, to service the borrowing from the banks.
So, government is borrowing money from the banks that it gave them to keep them viable. And we pay. Is this a scam or not?
