You gotta stop thinking of it as a left/right thing. It doesn't exist. It's clouding your perspective. Populists vs establishment might be a better way to categorize if you needed just two groups, but that's still too simplistic.

The world is a messy place with lots of different groups trying to get power, enrich themselves, and push their ideology. Whatever ideology a group is pushing has little to do with having the moral high ground and will typically result in their own benefit.
