Tom Streihorst, in an essay published in the Los Angeles Review of Books:
Ask any entrepreneur, and he will tell you making stuff, be it specialty steel, a low budget movie, saltimbocca a la romana, a collateralized loan obligation, a back massage, or an oil tanker is the fun part. It is selling it that keeps you up at night, breaks your heart, drives you into bankruptcy. That is why salesmen get paid more than engineers. Our problems today are purely problems of demand.
