Modern Money Theory is honest in it's understanding of how fiat and debt / banks and central banks really work. They think the money printing is just lovely and as you post I use their argument that we could do away with regressive taxes or even all taxes and just print money enough for every one and every thing if they and lakey liberals were right. Problem is the systems and services of the world build up around a premise or base which works fine, as long as there are no sudden changes, but there always are black swan disruptions that come blind side and knock down the houses of cards. The internet bubble fueled by Greenspan's Y2K paranoia then Sept 11 2001 caused more crank up to the easy money houses for everyone craziness and near crash after near total financial system crash we have arrived at the final game. QE and world wide finances are now based on years of the U.S. Fed, and the rest, supplying billions a month in money out of thin air. Will the end of QE come without another crash? How could it? It will just go on and on because they can't get out.
