I don't think Stephanie Kelton is attending Bohemian Grove, I think she just needed something to write her phd about.

MMT also dosn't propose hyperinflation as a matter of theory. Instead of congress taxing a fixed amount and the fed monkeying with the money supply on the back end to target 2% inflation, MMT wants the fed to print all the money on the front end and congress to dynamically adjust the tax rates in real time to pull cash out of the economy to target inflation.

Of course for that to work, congress would have to light all of the taxes on fire upon receipt, and when has congress ever been able to resist spending money? So it's only inherently inflationary if you subscribe to public choice theory, or generally recognized government's inability to achieve competence.

The fundamental error MMT makes is that it misunderstands the nature of money and value. MMT thinks that if you spend a dollar on something, then by definition it is worth a dollar. That is (to a nearest approximation) true for voluntary market transactions, but not for government expenditures, which can be (and often are) negative value add.
