There are definitely some good reasons to stay in school, but this article rubbed me the wrong way. Take for example, a couple of the arguments presented:
Argument: You get a lot of valuable social connections from being in school. Counterargument: You will meet others and learn from your peers by surrounding yourself by smart interesting people, but this doesn't have to be at a university. Why not connect with smart ambitious people of all ages that are working in your field? If the main value of elite colleges is that they screen bright students and bring them together for 40K a year, the students are getting ripped off.
Argument: Mark Zuckerberg was successful because he was vetted and educated by Harvard. Counterargument: This seems highly unlikely. No one used Facebook because they knew the developer was Harvard educated. And, Zuckerberg was an accomplished hacker before he came to Harvard.
Argument: Most successful entrepreneurs are not drop outs. Counterargument: That is because most people who try entrepreneurship are not drop outs. A better question is whether drop outs who start businesses are more or less likely to succeed. An even better question, is whether the same person is more likely to succeed if he/she drops out. Unfortunately, the last question is impossible to answer.
