Atlas Shrugged, more charitably perhaps despite its manifest flaws, seemed to me to be about the dangers of putting “the needs of the many” over individual rights, and how it can ultimately be self defeating for the whole.
I don’t think, “too much equality” was one of the themes. Rather, it was about too much centralized power over the individual. And yes I do think that’s somewhat relevant to understanding issues of today, including mass surveillance the centralization of technological control behind crypto-nationalized zaibatsus, etc.
