in practice it turns out that many conservatives are unwilling to concede that Keynesian macro has any validity to it, or that you can sometimes run the printing presses without unleashing runaway inflation, because they fear that any such admission would open the doors to much wider government intervention. But that’s exactly my point! They’re letting their views about how the world works be dictated by their vision of the kind of society they want; they’re politicizing their economic analysis. And that’s why they keep getting everything wrong.
This is why we can not have a policy discussion. Because one side doesn’t care about how the world actually works, only the kind of world they wish to live in.
