It may just be easier to get rich if you're fucked in the head already. Risk avoidance? That's the sign of a smart person, but most ways for a poor to become a rich are far more likely to fail than succeed. Empathy? Healthy, but that'd stop you from stepping on people on the way up.

Especially as a writer, idk about other countries but the USA's literacy levels are abysmal (half the population reads at a 10 year old's level or worse!), so an idiot would have the largest audience.
