Oh no, god forbid you have to live off of $50,000 post-tax, post-loan debt! Why, that's as much as the average FAMILY makes PRE-TAX, how horrific! And to think that's your starting income too! Why, $50,000 of post-tax, post-loan debt money would barely be enough to buy a three story house in a nice suburb, send your kids to private school, and still have money left over for things like HDTVs, iPads, and vacations. And to think the only compensation you get for such a lifestyle is that you get to work your dream job; what must thou have done to antagonize fate?!
As a guy planning on going into academic research which promises a lucrative $60k-$80k pre-tax income for most of my career (assuming I can keep funding my own salary), you have my full sympathies. Truly, physicians are the paupers of our society.
And this why people should take cost of living into consideration of where they attend. For example, San Francisco is my favorite city in the world and I have family who lives there, but I'd still be very wary of applying to UCSF simply because of the outrageous housing prices there (although I believe UCSF does have student housing which would, I hope, make it possible to live there without paying $2000/month just on rent). On the opposite end of the spectrum you have a school like Emory where housing prices are dirt cheap, especially if you don't mind making a longer commute.
Also, if you live in a city with housing prices of $1500+ for a single bedroom apartment, chances are that city is pretty dense. If that's the case, you can live without a car, and you'll probably want to anyway even if money isn't a concern. So that cuts your gas, car payments, and insurance costs out of your living expenses which will help to compensate for the higher rent.
All that said, having to take out $25k a year to live off of is still pretty reasonable unless you don't mind living in a ghetto apartment, driving a 1985 civic, and subsisting off of ramen during the entire time you're in med school.
