This is woefully misguided. I'd much rather have a Harvard MBA and have access to that network than be a YC alum and have access to that network. A top MBA buys you instant credibility with business people (i.e. potential customers), it exposes you to the business needs of a wide variety of fields (i.e. potential products/services), and it gives you access to a wide variety of people who can help you out, not just with the ins-and-outs of running a startup, but with financial issues, management issues, legal issues, and the whole range of topics that affect a small business.

I also found one quote interesting because it reflects such a myopic view of entrepreneurship: "Despite everything learned about business in MBA programs only 5% of graduates go on to start a business upon graduation!" It seems that in the author's mind, the only potential entrepreneurs are fresh graduates (i.e. people who don't know anything about anything). Did it occur to the author that many people go into an industry, learn how it works and build a network, then start a business once they have a strong foundation in place? Maybe that's not how your typical web startup works, but there is a whole world of entrepreneurship beyond that niche.
