Good calculation. Here's something to think about also; next time you go to your teaching/university hospital, you'll likely be seen by residents- they've graduated med school, but can't practice on their own just yet (still in training for that specialty).
When you do the math, many of your doctors are getting ~$10 an hour, maybe even less.
Pilots and doctors both start out getting the short end of the stick. It ain't right, but it's the way of the world. The hospital management abuses them just as much as airline management abuses pilots.
There's the same problem in both professions, everybody complains, but there is no unity, and so the situation will never change. If professionals want more, there must be unity.
