• If war can indeed be turned into a relic, then the virtue of greed will recede further. From a given society's standpoint, one big upside of wanton material acquisition has traditionally been the way it drives technological progress-which, after all, helps keep societies strong.

But if societies no longer face conquest, breakneck technological advance is an offer they can refuse, and frugality a luxury people can afford.
