All levels of employment, in the human world, are based on intelligence. The smarter you are, the less actual work you have to do. Meaning, if you do manual labor for a living, or you have some other stressful job you hate but you're not smart enough to rise beyond that level of employment and you "gotta pay bills", guess what, you're a fucking moron. The smartest people at the top of the food chain don't really work at all.
