Communism
No reason to be jealous. You can all be the SAME!
Have you ever envied someone?
There's no reason to envy someone ever again! Communism is based on the values that society should be perfect and everyone should be the same. The perfect utopian community! Since everyone is equal, there are no classes to divide anyone.
This system was created in part by Karl Marx. He was a German philosopher that helped to write The Communist Manifesto. This philosophy became popular because many workers desired equality with their rich counterparts. This philosophy does not exist (because it is a "perfect" society). A utopia is quite similar though. Many utopias have been created but have not lasted very long, because complete equality is extremely difficult to maintain and achieve.
