Economics in one lesson is definitely a very good book for beginners, but surely not sufficient to fully understand economics. Human Action is the best book to get a full glance on economics. However, it’s not easy to read.
Principles of Economics is a masterpiece. Saifedean read all relevant austrian economists like Mises, Hayek, Menger, Rothbard, Hazlitt, Hoppe, etc and puts all his knowledge into an easy to read format.
Doesn’t make sense that you like Economics in one lesson but dislike Principles of Economics. Both authors have the same mindset and teach the same economics (austrian).
