“When a resource is easy to control and extract, whoever does the controlling also does the ruling, and they don’t need to share it with anybody. Well, just enough to keep people quiet and content. So corruption is rampant, inflation destroys other industries, citizens live off of government handouts, and these countries develop little else to offer to the world.”
