I'd refine your opener to:

- economists have a good idea of how economies have worked _to date_ - they posit new policy to achieve goals - these policies introduce second-order effects that they failed to predict

I mean, Friedman's criticism of Keynes was excellent, and forsooth, his policies made stonks go up. But i don't think there economy is any better for them; i think we are, broadly, worse off.

I support LVT, but there will be second-order effects. I guess we are doomed to lurch from crisis to crisis, at a higher level than economic boom-and-bust.
