I graduated with a Psychology degree. I worked at a lot of BS jobs after college from recruiting and customer service which lead me to pursue sales for more money. Did sales for about seven years for various industries, left sales about two years ago, and now I work in totally different field that funny enough isn't customer facing. Being under 40, I'm proud to say that I am very close to what I feel is financial freedom.
Anecdotally, one of my friend circles consists of some engineers, doctors, lawyers, CEOs - you get it, the book smart people. Very well educated, went to prestigious universities, earned their highly respected degrees, etc. Most of them today are solidly traffic jammed in the rat race like the majority of society.
I have another friend circle, not nearly as educated as the friends highlighted above, who some are sitting on multi-million stock portfolios/assets/whatever. One of them who really stands out paid one of our other friend to write all his papers in college. Think he barely squeezed out a C average.
It really depends on the person. I work for an Elon Musk company if anyone cares.
