This means that there is only so much wealth in the world, and, in many cases, the more others have, the less you have. This line of reasoning gives Limbaugh apoplexy. He practically shouts on his program that wealth is not a zero-sum game. In fact, he says that the more the rich have, the more the poor will have, and only envious liberals claim otherwise. Sure, money is unlimited and it can multiply like crazy.
Devalued money does trickle down.
But there are only so many things in the world. Like the land you are on, the home you live in, or even the air you breathe. Homes and Land Property and land are the classic examples of the zero-sum nature of wealth. Except for brief periods at the ends of speculative binges, the prices of land, homes and other kinds of property only go up. You already know that one of the fastest ways to get richer is to have enough money to hoard land and property.
