Anybody talking about it ... anyone?
MMT is like Keynesianism - great theories with fatal assumptions. The fatal assumptions are not about the workings of the economy, but about the workings of humans.
Keynes assumes we will raise taxes in good times to repay the debt generated, according to Keynesian theory, in bad times.
MMT leads to inflation and assumes we will raise taxes to fight that inflation.
Interesting thoughts, but those behaviors are simply not on the list of behaviors available to elected politicians.
Maybe in a different universe ...
