‘Austrian’ Economics explains the real world since it deals with purposeful human action, unlike the fantasy models put forth by other economic schools.
The only two schools (colleges) I know of that still takes the Austrian school seriously are Grove City College in PA and Hillsdale College in Michigan ( the former still has the original papers written by Ludwig Von Mises kept in their Library Museum ). Both schools only have undergraduate programs however.
NYU still teaches it but simply as an afterthought.
There used to be a time when Milton Friedman was alive that the University of Chicago School of Economics took it seriously. I’m not sure anymore today.
