I think what irks me about it is that a hell of a lot of jobs - OK, maybe not driving a bus or stacking shelves, but a lot of jobs all the same - involve a good deal of creativity, at least if you want to do them properly. It's hard to be a good teacher without being creative, I think. Science, maths, engineering and research medicine are immensely creative, yet these are the stereotypical "nerd" subjects that are viewed as the polar opposite of anything cool, arty or 'creative'. Hell, you can write software creatively (and not just in terms of flashy graphical applications, I mean, but in terms of the actual code).
But we have this kind of collective cultural tunnel vision that assumes a 'creative' job means doing something to do with images, music or, at a pinch, writing fiction of some sort. I'm not dissing any of those things per se, of course - the people who do them may be good, bad or indifferent, same as any job - I just think it's unwarranted to put them on this 'creative' pedestal when what they do is often no more creative than what a lot of other people do, without receiving the same cachet for it.
