Another source of malinvestment has been the business cycle triggered by the credit expansion of the semi-public fractional reserve banking system. After the financial crisis of 2008, malinvestments were only partially liquidated. The investors that had financed the malinvestments such as overextended car producers and mortgage lenders were bailed out by governments; be it directly through capital infusions or indirectly through subsidies and public works. The bursting of the housing bubble caused losses for the banking system, but the banking system did not assume these losses in full because it was bailed out by governments worldwide. Consequently, bad debts were shifted from the private to the public sector, but they did not disappear. In time, new bad debts were created through an increase in public welfare spending such as unemployment benefits and a myriad of “stimulus” programs. Government debt exploded.
