Steven Plaut lays it out in Frontpage Mag:
There is a fundamental difference between economists and lawyers (or legal scholars) when it comes to resolving complex social and economic problems. Economists believe that human behavior and the functioning of institutions are based upon incentives. Lawyers and legal types believe that one can resolve complex problems by passing laws and imposing regulations. The latter think one can legislate away the problem.
I like to describe the approach by lawyer-types to such problems as “rain laws.” They are like trying to resolve the problem of flooding from heavy rainfall by means of a law making it illegal for it to rain.
