Not currency.

Money.

Inflation is a leftist invention. It’s caused by infinite printing of currency. All you have to do is not print more currency than you have money.

Money is specie. You can’t create it out of thin air. Currency was only created to be a claim check to money, because carrying money around is heavy (and somewhat dangerous). When there’s more currency than there is money, that’s adulteration (and was generally punished by death when the bankers who did it were caught).

Now they create currency every time a loan is written. Inflation only happens because of this.
