I know inflation is dependent on a lot of variables, but is the ever steady rise due to greed?
Well, there would be less inflation if people didn't aim for profit
Sure, that has been said since the classical era. The money falls from the sky, then the greed gets started. It's called a bubble, or boom and bust.
In economic terms there's no such thing as greed. There is only "demand". The cause of this demand is up to you to research..
Oh, yes.... That is probably one of the MAJOR reasons inflation is so bad in certain places.
