The last few paragraphs of the article really brought an interesting light onto the subject. Most of the people I know who left college to start a business or to work somewhere in Silicon Valley had a remarkably privileged upbringing. They never had the worries about the financial or temporal investment into an education or any experience taking risks. I'm not trying to berate people who drop out of college for these reasons, but it's an important factor to keep in mind when truly analyzing their success.
