There needs to be 2 extremities for money to work/flow, the extremely rich and the extremely poor.
This is a false premise you have been indoctrinated with. Extreme wealth is not a product of great contribution but of an extraction process. If you don't understand this as the new reality, you will never fully understand the manufactured hardships/nuisances in your life. Extreme poverty mutes the vitality of a population, inhibits competition and progress and endangers everyones safety and well being. When you remove the ability to compete, you create rent takers and not innovators.
The societies of the world as we know it would crumble completely if everyone were equal.
I never said complete equality was possible or even desirable. Advantages must be given to the most able because without a reward system, there is no impetus for progress but it must be checked before it becomes what it has become today, a compendium of shadowy oligarchs doing as they will and perverting every democracy. Have you really considered the state of the world today?
