Well, I don't think that's necessarily true. Writers and musicians: have you been reading the internet at all lately? Doctors, lawyers: these activities necessarily involve working on/with someone and involve a massive amount of trust due to the amount of responsibility involved. This is why there are necessary qualifications before you can call yourself a doctor or a lawyer. Once you have those qualifications, it's not so hard to find someone to pay you for it, although even then people do it for free. (aid work, pro bono legal work) Carpenters: you're way off. I know fully trained carpenters whose main job is something else and they do carpentry in their spare time. Don't forget the results of that labour aren't as readily duplicated as anything in purely digital form, so visibility isn't going to be anywhere near as high. You can't just upload that chair to WoodForge. Chemists (or any "hard" science): uhhh, grad school? MBA: yeah, you got me on that one :)
