MMT basically posits that the wise and incorruptible solons in government should create as much currency as they think is needed, spend it in areas they like, and solve any problems that occur with more laws and regulations. It’s nothing new. Just a more radical version of the economic fascism that’s dominated the U.S. since at least the days of the New Deal. It’s just another name for an old, and very stupid, set of economic ideas. By stupid I mean, “showing an inability to predict the indirect and delayed consequences of actions.”
