In 2010, tens of thousands of overqualified MBAs will emerge with nowhere exciting to go. A very few will land jobs in investment banking, but those who want grand jobs in big companies or consultancies will be disappointed. Increasingly they will go crawling back to their old employers to do pretty much whatever they were doing before for pretty much the same money. As the efficacy of a business school is measured according to the salary one gets when one finishes, both students and employers will question whether it is really worth the $160,000 that a top MBA costs.
