One timeless and universal truth that I saw go back as far as I studied history, since before Confucius who lived around 500 BCE, is that those societies that draw on the widest range of people and give them responsibilities based on their merits rather than privileges are the most sustainably successful because 1) they find the best talent to do their jobs well, 2) they have diversity of perspectives, and 3) they are perceived as the fairest, which fosters social stability.
