Would changing the interview and selection process to look like other jobs alleviate the case you're laying out?
In a similar way, there are students who spend $200k to go to college, then go to law school, wanting to practice in a certain area of law, and find out at the end that the only job they can get is poorly paying or in an area they don't want to live.
The difference is that even if you fail to get a job as a lawyer, you can start your own practice. With medicine if you cannot get residency first year, your chances of getting in drop significantly after that and you can never go out and practise medicine on your own.
