The term from classical politics that comes closest to describing something ancient thinkers hadn't foreseen: the rule of the world by multinational corporations and their rich shareholders. It's not always a benevolent regime. The problem isn't so much with economic self-interest but with tunnel vision, as corporations and their shareholders tend to overlook long-term progress, even their own, and instead focus all their energies on improving the next quarterly report. The outcome tends to be disaster.
