I believe the left vs right terminology is only useful at getting the working class to attack each other. We should be using phrasing like "rich vs poor".

Yes I know that ends up meaning right vs left, but my god the right are so much better at branding and propaganda and manipulating people's minds, it's time we learned from that.

IMO ideally the center should be fine with government provided socialized services and regulation to fully support society, offer everyone the same advantages to change their economic status to middle-class, and prevent wild disparity and capture of the system by wealth yet still allow for people to achieve wealth that, does indeed, allow for some excess but not at the expense of society.
