Not all MBA degrees are created equal. For example, ones from top US schools such as Booth (U Chicago) or Wharton (U of Penn) should be significantly more valuable -- even on a cost-adjusted basis -- than ones from Rotman (U of T) and Ivey (Western) which, in turn, should be more valuable than ones from Sauder and Molson. As such, the cost-benefit analysis should be done with the right scope. One key consideration is that for schools in certain brackets, the value of the MBA has been more diluted vs. in others -- and the dilution isn't linear.
