Who do these type of anti-MBA sentiments apply to? Do a lot of people enroll in MBA programs to "learn business" so they can start a startup, or do they enter MBA programs to learn management so they can get a job in corporate America? I've always assumed its much more the latter. I could be wrong, but I don't think McKinsey is going to be terribly impressed with a sole story of "learning lots" from launching an App Store app. I think its good advice for people entering MBA programs for the wrong reasons, but I'm just not sure how large that segment is vs. traditional MBA students.
