@GhostOnTheHalfShell @economics-that-works There is also a velocity effect. Currency at rest is worth less than currency in motion. Enforced inflation rewards private hoards, which affect the velocity of money nearest to them. In this, the fiat controller is barely distinguishable from a hoard of nigh-infinite fiscal mass.
TL;DR: the value of money is not constant, and it is frequently manipulated to unfairly get more goods and services out of us.
