Possibly, but someone qualified enough to be a good programmer could probably also make way more in a financial or medical field. Having the ability doesn't necessarily correlate to having an interest. Many smart people may choose to repair computers because of the interaction with a variety of people daily rather than stuck in a cubicle somewhere.

Hell, I could make more money as a dentist, but I don't find the idea of poking around in people's mouths every day to be very appealing.
