To be frank, I completely disagree, and I get the feeling that so do most people, actually. We don't call it "work" because it's pleasant and fun. I see this as someone who finds his job genuinely engaging and almost, though not quite, a benefit to society, and whose alternate career paths would potentially involve more benefit to society and even more engagement in my work. My job would actually be fun if not for the unpleasant necessities involved in treating it as business that actually has to ship a product some day, which is of course exactly what makes it at all useful to society and not just a shared team hobby.

Of course, the alternate career path would also involve significantly longer hours for significantly lower pay (ie: going back into academia), which brings us right back around to the point that it's called work because you don't like doing so damn much of it.

Also, it really would have helped to segment out the statistics by income and education levels. Remember, the arithmetic average of a power-law distribution does not make sense.
