My way of trading is to know that the joy you give me is paid for by the joy you get from me – not by your suffering or mine. I don’t accept sacrifices and I don’t make them. If you asked me for more than you meant to me, I would refuse. If you asked me to give up the railroad, I’d leave you. If ever the pleasure of one has to be bought by the pain of the other, there better be no trade at all. A trade by which one gains and the other loses is a fraud.
