I have just finished reading a detailed critique of Atlas Shrugged:
https://www.patheos.com/blogs/daylightatheism/series/atlas-shrugged/ ... even the COBRA Commander dialogues at the end, although they drag a bit.
I'd recommend it (the critique, that is, although we are probably all old and wise enough to be able to read the book without being brainslugged) if you like that kind of thing.
What came as news to me was - I knew enough about the book to know that Rand's heroes are loathsome and amoral by conventional standards, but what I didn't appreciate was that _Rand's_ standards are wildly inconsistently applied; we're three chapters in when we're told approvingly "Desperate for funds, with the construction of [the protag's grandfather's] line suspended, he threw down three flights of stairs a distinguished gentleman who offered him a loan from the government."
They steal, they cheat, they bribe, they initiate force with gay abandon, they sometimes give their friends absurdly sweetheart deals, and of course they all end up at the end living in a collective society. Conversely, sometimes the villains' villainy is demonstrated by them squeezing the harshest possible deal out of the heroes... but isn't that what Randoid supermen [1] are supposed to do?
The second surprise was that although the book is taken by its advocates as outlining a realistic philosophy, a sensible way to act in the face of a scenario they believe is already happening, the plot does depend on someone inventing a perpetual motion machine and a cloaking device, and someone else finding a Garden of Eden with everything one might want in it.
The third thing that struck me is this: whenever anyone does anything nice, today's edgelords dismiss it as "virtue signalling", apparently because it is inconcievable to them that anyone might do something nice because they want to do something nice.
However, to Rand altruism is an ever-present danger. She felt about it much as Jack Chick felt about works salvation. The Randoid supermen are distinguished as supermen not least because they can resist the temptation of altruism, a gateway sin toleration of which will inevitably cause society's collapse into a communist dystopia.
[1] all of whom are white except one who's nominally Latino but explicitly described as being pretty darn white, and usually blonde and blue-eyed. As opposed to the villains who are all ugly and I'm pretty sure some of them are described as having especially big noses, by which I'm sure Rand might have meant literally anything.
