I looked into this new concept, that taxation isn't about funding the government but is about controlling inflation. It comes from the MMT, variously named either Modern Money Theory, Modern Monetary Theory, or Magic Money Tree. It is based on the current ahistorical position that currency is printed out of nothing by central banks.
What's funny is even Daily Kos was accurate in their criticisms of it, and they're almost always wrong when it comes to economics.
Boring, Stupid, Wrong: MMT
Here's a more detailed analysis by a more professional source.
Weekender: The Trouble With Modern Monetary Theory (MMT)
You obviously didn't look very hard, as your own source explicitly states that "If you just take those two elements and run with them, you've proposed nothing that should surprise anyone with 6 credits' worth of undergraduate economics courses."; In other words, that "in a fiat-money system, the government can always create as much money as it wants, and subsequently control the money supply by taxation" is,
according to your source, so
obviously true as to barely be worth saying.
It then goes on to talk about MMT, which (it claims) is based around this statement of the obvious - but clearly is not THE SAME THING, as it is being declared to be incorrect - and indeed, insofar as MMT actually does make the claim that "no matter how much [money] we make, we needn't worry about making too much. Ever.", it would be hopelessly wrong - and as such the exact opposite of so
obviously true as to barely be worth saying.
You need to decide what it is you are opposing here.
Are you opposing the claim that in a fiat-money system, the government can always create as much money as it wants, and subsequently control the money supply by taxation? If so, your source here is declaring you to be OBVIOUSLY and completely wrong, because according to your source, this is so self evidently true that it "should surprise anyone with 6 credits' worth of undergraduate economics courses". And yet you seem to believe it to be false.
Or are you opposing the claim that no matter how much money we make, we needn't worry about making too much? If so, you need to first find someone who is making that claim, before it is reasonable to oppose it; Certainly nothing any of your correspondents in this thread have said can be construed as making such an obviously false claim. So the question becomes 'Why are you fighting a strawman'?
I would suggest that this 'new' concept - that taxation isn't about funding the government but is about controlling inflation - does NOT
come from MMT, but is rather one of the axioms upon which MMT appears to be constructed. Certainly my understanding of the concept cannot come from MMT, because I have no idea what MMT actually says (other than what your source above claims it to say). I have understood this concept based on a variety of sources and a knowledge base built up over many years; I have never knowingly studied or been exposed to the details of anything calling itself MMT, so arguing against this theory in no way constitutes any kind of argument against my position.
Still, it's always amusing when someone presents, as evidence for their position, an article claiming that their opponent's position is so bloody obviously true as to be barely worthy of mention.
