Henry Ford made a lot of money making cars at one time, but that was a small advantage to him compared to the benefit to millions of people who for the first time in their lives were emancipated from common public carriers and could live where they wanted, move at the hours they wanted, to the places they wanted. Ford collected a billion bucks, but that was peanuts compared to the benefits.

I started working and publishing in price theory by 1938.

It was in the 1960s that I began the detailed study of public regulation.
