There are a few thousand other books you should read - going back to Plato. You should also understand linear algebra and multivariate calculus. You should understand the equations in economics - even for the economics you disapprove of. This means working through people like Von Mises and Fridman that are enemies of socialism. If you want a meaningful framework through which economics should be approached mathematically you should read Brian Arthur as he was the first economist (to my knowledge) to apply dif frac calc and path dependencies into models.
So if by educated you mean you've read a few thousand books dating back to Athens and have a highly developed understanding of mathematics, history and economics then cool. If you mean you read some "Marxist" books and you've somehow a great command of human knowledge then go crawl under a fucking rock please.
All hail /u/Yeuph, master of a thousand other books you should read
You could honestly read the core works of the past 3 millennium in like a year at a leisurely pace of like 3-4 hours a day reading.
Most of those will probably be published in the past 200 years too lol
