Banks weren't meant to be like this

Michael Hudson gives a short history:

The first step toward today’s mutual interdependence between high finance and government was for central banks to act as lenders of last resort to mitigate the liquidity crises that periodically resulted from the banks’ privilege of credit creation. In due course governments also provided public deposit insurance, recognizing the need to mobilize and recycle savings into capital investment as the Industrial Revolution gained momentum. In exchange for this support, they regulated banks as public utilities.

Over time, banks have sought to disable this regulatory oversight, even to the point of decriminalizing fraud. Sponsoring an ideological attack on government, they accuse public bureaucracies of “distorting” free markets (by which they mean markets free for predatory behavior). The financial sector is now making its move to concentrate planning in its own hands.
