I can't really see Ayn Rand as anything other than far right, and that's about as OG libertarian as you get. Free market, unfettered capitalism.

I agree with the premise that late stage capitalism is a cancer, but I do have to say this particular scale of productivity/wage doesn't necessarily imply effort/wage directly. Tooling and technology has also improved productivity and in some cases has made jobs far less effort than they once were; arguably a good portion of profits were paid to who developed those solutions.

I don't have a better comparison to offer unfortunately, just a small blind spot in the data I think is worth mentioning.
