I think it's a lot more valuable to study something
else and apply that to IT. If we were in the early 90s, then knowledge of programming, web development, networking, or general tech support would be very valuable and you'd be very employable. But we're not. It's 2009 and programmers are a dime a dozen, there's no shortage of web designers, and demand for tech support decreases every year. See
this report for more details. In the UK, tech support generally pays around £27,000 a year.
A much more valuable strategy is to have some other skill, and then a proficiency in IT will greatly increase the value in that skill. Proficiency in IT alone really isn't worth very much. Some of this may be academic, such as knowledge of economics, mathematics, chemistry, physics, engineering - all of which require degrees. A tech savvy physicist is worth a lot, in a huge variety of industries. I often ask my friends to write me some pretty simple code for all sorts of data analysis and stuff. If I weren't in academia, I'd probably have to pay them for that.
Some of it might be vocational, such as art, design, management, business studies, and some of it is simply people skills. Someone that is good at organising people, with a knowledge of IT, is incredibly valuable (a chief technical officer earns about £100,000 a year).
In general, I'd say IT skills complement other skills to a high degree, though IT skills alone are only going to decrease in value.
