"One telling statistic to emerge: only 6% of this year's graduating class of MBAs from Harvard Business School chose to go into investment management. This is the smallest number since records, released by Soifer Consulting, have been kept. Twice this proportion of Harvard MBAs wanted to be investment managers in 2011. Instead far more head for private equity and venture capital."
From LEX - "The upfront and opportunity cost of a full-time programme at the top 100 schools is about $200,000...An MBA graduate would need to maintain a gross salary premium of $30,000 a year for 10 years just to recoup their investment."
