I'm not saying "therefore capitalism is the right answer" (though I still think it is). I'm not saying that people shouldn't be interested in other systems. But I am saying that it matters a great deal that the "other system" be better, not just different. As my co-worker Steve Hanka used to say, "There's lots of ways to do it that don't work". There's lots of ways to structure the economy that work out worse; let's not make things worse by trying to make them better.
