I've a nephew who did what she more-or-less recommends, dropped out of college to go work in computers. The DrsC tried hard to convince him to finish, all in vain.
In vain, that is, until the economy crashed and he lost his high-paying job. Then he found that in a tough economy people with his skills and a degree were getting the IT interviews and jobs, he wasn't. Then he finished his degree.
It turns out that requiring particular colleges, degrees and majors is a quick-and-dirty way for HR units to winnow an overwhelming stack of applicants into a manageable number to screen for hiring. Count on them to hire these supposedly "more qualified" applicants in less-than-boom times. Which is why your children should finish their degrees.
