This is a good start:
MMT requires the government to raise taxes once inflation starts rising due to previous money printing.
What are governments doing now? They are actually thinking of handing out more money to people to offset the effects of inflation (thereby making the inflation worse).
In other words, MMT requires governments to always do the right thing, which they don't.
That's ignoring the theoretical underpinnings of MMT which are by no means unassailable.
That’s a common misconception. Have you seen any MMT economist advocate a tax increase recently?
Here is an excellent podcast with one of the most eminent MMT scholars Randall Wray discussing his recent publication on how to deal with inflation in the US currently:

> MMT, for those who aren’t familiar with it, is a small, cohesive group of people who go around telling the government to borrow more and spend more.
Which is fundamentally incorrect and betrays a misunderstanding of MMT so his opinion is irrelevant
The Federal Reserve (by far the most important one) is privately owned, as are Belgium, Greece, Japan, South Africa, Switzerland, Turkey and the Bank of Italy.
The ECB is owned by central banks of member states, some of which are privately owned.
Private ownership is any case one issue, the other is the fact the CBs are structured in such a way to be resistant to political pressure and (meaningful) oversight.
