While financial incentives are a very complicated business, two simple points hold true. First, even without payment, some folk will always record music, write software, make their feature films, do their own investigative journalism, occasionally even test their own drugs. You couldn’t stop them if you tried. Second, we will all be better off with more, not fewer, professional careers available for knowledge producers. Not having to stick with a day job allows creative workers to be more creative and productive, for the benefit of all.
