This post pretty much entirely relies on the assumption that work and interests are mutually exclusive. I think with most people, that is true, but there are a few lucky ones where this isn't the case. In my personal experience, those that are still connected with their interests are the lucky ones who have managed to find or make a profession that truly interests them. I've never been to Burning Man, but, I sort of suspect that a lot of the attendees are these sorts of people; they still have well defined interests and passions. That suggests they don't have a soul sucking job, as they still have a soul.
