'The low IQ answer of "corporate greed" is generally only coming from progressives. I say, low IQ because OBVIOUSLY corporate greed is ALWAYS a factor. Calling that an explanation for inflation is like blaming gravity for a plane crash.'

Prior to the neoliberal deregulation of banking commercial banks were required to only finance productive purposes when they used their central bank backed privilege to issue new money into circulation when providing fractional reserve debt funding. Since the neoliberal deregulation that requirement was removed and so the corporate bankers moved to fund non productive purposes because they now could. Most of that non productive fiat debt monetary issuance (inflation in the true sense as you point out) is toward real estate- mostly residential housing- corporate bankers have become parasitic rentseekers by financing non productive real estate asset price inflation. At the same time they fund a lot less productive purposes because that harder and riskier than real estate financing and so the quid pro quo of fiat debt issuance that existed prior to neoliberalism is much reduced- the inflation in money supply caused by bankers fiat debt financing is much less compensated for by increased productivity.

Neoliberal deregulation enabled and empowered corporate bankers and speculators to misuse fiat debt funding monetary issuance and they quite predictably became parasitic rentseeking leeches upon the economies of the western world.

Libertarians as the new neoliberals don't seem to get this.
