Most people believe capitalism is a compromise with selfish human nature. As Adam Smith put it, "It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest." Capitalism works better than socialism, according to this thinking, only because we are not kind and generous enough to make socialism work. If we were saints, we would be socialists.
In Why Not Capitalism?, Jason Brennan attacks this widely held belief, arguing that capitalism would remain the best system even if we were morally perfect. Even then, private property and free markets would be the best way to realize mutual cooperation, social justice, harmony, and prosperity. Socialists seek to capture the moral high ground by showing that ideal socialism is morally superior to realistic capitalism. But, Brennan responds, ideal capitalism is superior to ideal socialism, and so capitalism beats socialism at every level.
