that's not really true, all economics is political and mmt is dripping with reformism trying to solve the problems of capitalism in the sphere of distribution instead of production

Sometimes some crappy pseudo leftist political parties push it like that but in a marxist context it doesn't have to be.

In the lower phase of socialism you're still gonna have money, and MMT seems to be the most coherent idea on how to handle money, that's it. It's a tool, not an ideology in of itself.

The real problem with MMT isn't that it's reformist, it's that not that many countries today have truly sovereign currencies.
