theodp writes "Over at TechCrunch, Vivek Wadhwa offers some don't-be-a-fool-stay-in-school advice to students that sounds a bit like an old-school Mr. T PSA. TechCrunch CEO Michael Arrington's questioning of whether students need to get any degree or go to college at all may sound appealing — dropouts Mark Zuckerberg and Bill Gates did do alright for themselves — but Wadhwa gives some good reasons why you should probably take the school-is-for-chumps argument with a grain of salt. 'The harsh reality,' warns Wadhwa, is that for every Zuckerberg, there are a thousand who drop out of college and fail,' and many big companies won't even consider hiring you for that fallback job without a degree. And, believe it or not, you can still become a tech billionaire later in life even if you're cursed with a PhD." Tech entrepreneur Michael Robertson approaches this question slightly differently; here's an analysis he made a few years ago, with the conclusion that the college investment pays off only about half the time.
