Still, even for those with some knowledge of economics, the tenets of the modern monetary theory can make your head spin. The government does not tax its citizens to pay for federal spending. It taxes them to ensure they use the dollar and to help to regulate demand. Since the government prints the dollar, it can never run out of money and it need never balance its budget, not even to prevent the crowding out of private investment when the economy is humming along.I have a problem with the hyperbolic claims. It's Keynesiansism with some suspect claims tacked on employing the word "never." Perhaps it is a straw man. But they are right that we shouldn't be worrying about the deficit and that fiscal policy could take the place of monetary policy. The problem is politics and a corrupt elite. But monetary policy has offest fiscal austerity to some extent so I don't understand the MMTers who denigrate the focus on monetary policy. The more mainstream economists are right to focus on it.
Stephanie Kelton has a comment.
On a different point: MMT supports tax increases and/or spending cuts to address demand-pull inflation. No different from, say, Abba Lerner or Marriner Eccles.
The real point of departure for MMTers and textbook Keynesians is, I think, very much bound up in the loanable funds theory of the interest rate (the former rejecting and the latter accepting it). From that follow all sorts of differences re: fiscal sustainability. Scott Fullwiler has written brilliantly on this.
