At the University of Southern California, 23% of 2012 M.B.A. grads were still unemployed 3 months after graduation.

Imagine that you have been accepted to Harvard Business School. The ivy-covered buildings and high-powered faculty whisper that all you need to do is listen to your teachers, get good grades and work well with your peers. After two years, you’ll emerge ready to take the business world by storm. Once you have that degree, you’ll have it made.
But don’t kid yourself. What matters exponentially more than that M.B.A. is the set of skills and accomplishments that got you into business school in the first place. What if those same students, instead of spending two years and $174,400 at Harvard Business School, took the same amount of money and invested it in themselves? How would they compare after two years?
If you want a business education, the odds aren’t with you, unfortunately, in business school. Professors are rewarded for publishing journal articles, not for being good teachers. The other students are trying to get ahead of you. The development office is already assessing you for future donations. Administrators care about the metrics that will improve your school’s national ranking. None of these things actually helps you learn about business.
