Joke's on me

I went on a date with a MBA student this weekend and during our conversation he asked how our classes work (since we don't really get electives or any control over our schedule at all). I honestly had never looked at how many credit hours we take because it never seemed relevant. So I looked it up. I also looked up the requirements for the MBAs for comparison.

Total credit hours in 2 years for b-school: 57
Total credit hours in 2 yrs (pre-clinical) for med school: 97

Years it takes an MBA to earn back the debt and lost salary: 5
Years it takes an MD to earn back the debt and lost salary: 20-40
