The truth is that it is quite curious that they use that book in terms of teaching or analyzing economic things... I read it when I was about 15 years old... at that time I didn't like reading at all... and I remember that I started having abdominal pains. very strong they took me to the hospital and I ended up having surgery for appendicitis... while I was resting for at least 1 month I started searching in my home library... and I found that novel... I really recommend it, it's good👍. .and look now it's material to teach economics ☺️
