Benevolence isn’t inef­fi­cient and I’m a big fan of benev­o­lence. It’s just that it’s not enough. It’s okay for a group of twenty-five or fifty peo­ple where every­one knows every­one. But when you have 300 mil­lion in the US or 7 bil­lion in the world, if we were self-sufficient and we had to pro­duce every­thing for our­selves we’d all die, or 99% of us would die. So we have to coop­er­ate with each oth­er. But the only way to coop­er­ate with each oth­er in such large num­bers is through mar­kets.
