You go to business school because you need that MBA for your job or to switch jobs. It is not about learning. It is about networking (and partying) for two years.

If you want to be an entrepreneur, sitting in a lecture about entrepreneurship does nothing towards achieving your goal. The problem with business school and business theory is precisely what this guy thinks is a virtue: addressing the "why". In real business, and especially entrepreneurship, figuring out the answer to the why is the easy part (although consulting firms would have you believe otherwise until they collect their fees and leave behind a book of trite observations and obvious suggestions). Executing on that why is what matters. Execution is everything in business, and especially in entrepreneurship.
