While funny, naivity to power dynamics is constant. We never know who will rule. I even conservatives are extremely lured by revolution if they have a leader that is more "conservative" than the opposition.

This sounds wrong. Hierarchies are inevitable because there will always be differences among individuals. Leftists will design a society where these hierarchies will not be that astronomically high, to raise the bottom ceiling.

Or do you know any popular left leaning politician that advocates for full blown communism instead of just tax reform?

What you called a good point isnt, its diffamation of the left. And btw, imo full blown communism is equally delusional as busines-as-usual capitalism.

Alternatively, right-wingers work to elevate the minority at the top and left-wingers seek to raise the standards of those at the bottom.
