"The First Law of Petro-Politics,” which stipulates that the price of oil and the pace of freedom in petrolist states — states totally dependent on oil exports to run their economies — operate in an inverse correlation. As the price of oil goes down, the pace of freedom goes up because leaders have to educate and unleash their people to innovate and trade. As the price of oil goes up, the pace of freedom goes down because leaders just have to stick a pipe in the ground to stay in power."
