Aha, hermeneutics. The literal answer is probably found in the law of comparative advantage -- both Barry and Mark should do what they're best at doing. (Arguably this law is one of the handful of non-obvious insights from the science <sic> of economics.) A lot of markets are extremely price sensitive, but, OTOH, there seems to be a growing ratio of informed consumers that are not racing to the bottom, but instead acknowledge that a) almost every action has an ethical component that can / should be factored in, and b) how you spend your money has a greater impact than how you cast your 3-5 yearly vote.
