My father-in-law is an economist. He is insanely learned. I was reading Human Action years ago and I asked him what it would take to write a similar book today. I will never forget his answer…
"We can’t, we don’t know how to do it."
As far as I can tell, Hirofumi Uzawa was being completely serious when he said this and used to seriously believe it until he corresponded with Kenneth Arrow.
