Ask HN: What are some deep, mentality changing books?

I am talking about books like:

- The Sovereign Individual by James Dale Davidson

- How I Found Freedom in an Unfree World by Harry Browne

- The Bell Curve by Charles A. Murray and Richard Herrnstein

Books that make you go "hum....". It could be about Government, Money, Society, etc. Something very different from the modern-day "4 hour work week" garbage
