> If the fact that something has a marginal cost approaching $0 means you are morally obligated to provide it for a price approaching $0, why is there not a similar moral obligation to provide something that has a marginal cost of $3 for $3?
If it were up to me, it would be -- or roughly something like that. But I have supposedly radical views on a lot of things (FWIW I affiliate to a local socialist party). I think a lot of the decisions made by big pharmaceutical companies, retail corporations, etc. are morally reprehensible. To give you a more direct answer of why I do not go down the streets at night shouting for change on this: because it'll be much harder for me to achieve that change. It'll be much harder for me to be an influencing force of bringing about a system I would be happy with. But because I am someone of a technical background, this fight is the fight I choose to participate in. Also, charging something $3 for something that has a marginal cost of $3 sounds kind of lousy -- I'm sure there's got to be a more elegant way of doing that. :)
