Just as shonky US mortgages (money printing called credit) & CDOs were snuffed out by the GFC, our impending Depression will likely also snuff out MMT, IMO, because we're in for an economic tsunami as bad as the 1930s
Just tell the average stiff in the pub that the RBA can print as much money as it likes & dishes it out to individuals, companies & the Government willy nilly and you'll be told quick smart that you are in cuckoo-land!
