What our mainstream economists purposefully miss is the "origin" of modern money, which is almost universally a sovereign government acting as the monopoly issuer. Perhaps because most "economists" (at least the most acclaimed of them) get their paychecks from the elite of society, it is widely assumed that money originates with investors and business (capitalists) and there is little pushback to this falsehood.

Neoliberal politicians are very quick to answer any demand for better conditions or infrastructure with "how will you pay for it?". This insinuates that they are the "finders" of money when their authority to tax is totally separate from their authority to spend newly created money into existence. In fact, money must be first spent by the issuing government before it even available to collect as tax payments or borrow. Neither can be "funding" mechanisms and it is the spending of government that "funds" both.

Of course, the plebes are not capable of "real" self government when their economy is involved, so their "betters" must keep them fooled about the most basic economic truths lest they begin to demand that their government "coin" money for the public good as the Constitution mandates to pay for things like roads, schools, healthcare. etc. Should they discover that their government can "afford" anything that is for sale denominated in the currency it creates at will, even in the total absence of any "revenue" they might make the job of politician much more difficult and demand competency.
