What Is Inflation?

i want to talk about a paper that was produced by two economists at the d c. Federal reserve on why inflation happens, which is called, who killed the phillips curve and murder mystery. And it reveals something that's very, very important the current political situation, which is that both economists and like the rest of the ruling class in general, do not understand what inflation is. Inflation is literally just put when prices go up. If you think about it, like i a, that that's kind of the same thing, sort of, because if costs go up, your dollars are worth less money.
