I wasn't applying it to just economics. A political ideology doesn't have to be either wholly right or left. You can be socially left and economically right, right within your family but left within your community. Whatever mix you choose. It doesn't matter whether a separate system is right, left, or some mix. That's not the question. We're here to answer: What do right and left mean? What criteria do we use to determine if it is to the right or to the left?
Reactionary v. Revolutionary seems to work better than anything else. If it is reactionary, it is to the right. If it is revolutionary, it is to the left. Socially, economically, personally, professionally, publicly. Is there a reason this cannot be applied to every area?
Edit:
What are you thinking of?
Are you referencing Horseshoe theory with that post?
