Thanks for the answer, Levi. The job is no less risky just because you're doing it for free or at a discount. You have only so many years and minutes in your life in which you'll be capable of doing such challenging work, so I can see how a person would not wish to give away his life's blood to someone else he barely knows without adequate compensation. A value for value exchange would seem more fair. The question is, what value does that other person bring to the table? If I had the time, I would consider giving old retired military veterans a price break, as they made a sacrifice that I was never asked to make. So the value does not always have to be in dollars. Thanks again for sharing your thoughts.
