I don't really think that matters at all, it's just an old tenuous bragging point, he's just a guy with a tough looking face and maybe has an elementary understanding of economics that relies less on being accurate and more on the viewer agreeing with him about why everything feels broken. (not that everything isn't broken, or that those reasons aren't ever accurate, but it's just a classic grifter move to pull on the thread of truth till it unravels, like asmongold)

Crashcourse economics likely provides much more value to anyone really looking to learn.
