I found this interesting letter on Victor Niederhoffer site.
A letter from Donald J. Boudreaux to the New York Post
Falling gasoline prices are indeed welcome economic news ("It's a Gas! Pump Prices Fall to 6-Month Low," Sept. 13). But I worry about what these falling prices reveal about the ethics of American motorists. If rising gasoline prices are caused - as so many pundits and pols allege - by the greed of oil companies, must it not be true that falling prices are caused by the greed of consumers?
