I am sincerely sorry that you have met such “frum doctors”. Perhaps it is the company that you keep. They are certainly not the ones that I know, teaching and working in Universities in the US and Israel. Maybe on your next visit to your Alma Mater, you should stop in at the College of Physicians and Surgeons, and have a look at the folks with the kipot, and ask them a few questions.
Ask them about the all-nighters, and the time away form their families. Ask them about the student loans that they take to pay for Medical school, and the salaries that they receive for 60+ hour work-weeks, following 7+ years of studies. Studies that were primarily things like organic chemistry, anatomy, biochemistry, physiology, etc. Those do not leave much time for partying. Those were the kids cracking the books when everyone else went out. What did you major in, by the way?
You could also have a look around Israel, where doctors’ salaries are not exactly on par with their US colleagues, and ask them why they are in the field. Have a look at how much parting goes on in Israeli Universities–where the student all have jobs as well as their studies to contend with.
