One of the central problems, I feel, with Ayn Rand’s work in general, and Atlas Shrugged in particular, is that she was a very black-and-white thinker.
To her, any “governmental coercion” equals the Stalinist USSR.
Of course, I have hindsight she doesn’t have, but it is also my experience that Objectivist-inspired neocons have a convenient and peculiar way of historical interpretation.
So, after World War II, the United States was as close to a socialist democratic republic that we’d ever get, from the New Deal to the Marshall Plan, Keynesian economics held sway. The highest tax rate was around 95% both here and abroad.
