Left and Right are two sides of the same coin.
Good starting point for me was
https://en.wikipedia.org/wiki/Natural_law.
But that's a bit much...
Left and Right by necessity divide up/split certain parts of natural yearnings to get us arguing between ourselves so they can do whatever they want.
In the current state-of-things, I would say both Left and Right, by necessity, need a big government to succeed and in turn they become the criminals.
