"The fact that the world’s most prosperous and successful societies, the ones with the highest living standards and the highest levels of satisfaction among their people, happen to be those which have most closely approximated the liberal, progressive ideal that we talk about and have nurtured the talents and contributions of all their citizens. The fact that authoritarian governments have been shown time and time again to breed corruption, because they’re not accountable; to repress their people; to lose touch eventually with reality; to engage in bigger and bigger lies that ultimately result in economic and political and cultural and scientific stagnation. Look at history. Look at the facts. The fact that countries which rely on rabid nationalism and xenophobia and doctrines of tribal, racial, or religious superiority as their main organizing principle, the thing that holds people together – eventually those countries find themselves consumed by civil war or external war. Check the history books. The fact that technology cannot be put back in a bottle, so we’re stuck with the fact that we now live close together and populations are going to be moving, and environmental challenges are not going to go away on their own, so that the only way to effectively address problems like climate change or mass migration or pandemic disease will be to develop systems for more international cooperation, not less."
