I'd agree with that. I don't believe in the efficient market hypothesis. The "market" given his limited information, professorship salary, and the compensation offered him to do other work clearly showed a large spread which he was rational to exploit. I also believe society as a whole is being shortsighted in creating such a wide spread, but its not within his power to correct it; it's societies failure to think long term and his duty is to his family first.
