You don’t have to be bewildered with it, @crypto.piotr. It’s just another terminology manipulation, as it is usually done in the Centralized Hierarchical Political Matrix (CHPM). Orwell called it doublespeak. or newspeak You see, CHPM uses terminology to cover up repeating robbery. For example, at the beginning of the 20th Century, if you came to the bank to raise your money, and the bank could’t return your full amount and interest, that was called a Bankruptcy, or Default. Today it is called Negative Interest Rate Policy (NIRP)! In the 20th Century, excessive emission of the fiat money was called Inflation. Today it is called Quantitative Easing or REPO. MMT is just another name for a blind robbery created through the globalist economic system.

I would suggest to follow this man:

It's the job of politics to make people accept and live with, tolerate the economic system even when it gives them a rough shake.
— professor Richard Wolff

He is explaining it clearly and logically. You can start with these important lectures:
