Who says that the working class has to move up to the 1%?
I don't think that's what communists and socialist want. They want the 1% notched down to the 100%.
It's a combination of ignorance, jealousy, greed, laziness, and incompetence. Since they are completely incapable of reaching the 1%, then nobody should.
In the real world, nothing is like what wanna be communists claim.
It's even okay to be rich in Cuba today.
