Michael Lewis has a habit of... let’s say focusing on convenient facts to emphasize a narrative that doesn’t usually match reality. His books are entertaining (I think I’ve read them all), but they are actually a pretty bad way to learn about how the markets work.

The big short is a great book, but not sure it’s a good primer on how the financial system works for someone learning.

I would say that The Big Short is more impactful if you already have some general understanding of the markets.
