Have economists ever really gotten their story straight about anything? I don't mean to mock. They're doing a hard thing, and an important thing. But it's nearly impossible to do a rigorous experiment on anything they do, and there will always be evidence in favor of any position you want to hold. The number of variables is insane. Our decisions are always going to be based primarily on our best guesses. We can use economics to try to predict the problems that our best guesses are likely to give rise to, and mitigate them. But we may never get economics to give us a definitive answer to anything.
