From what I'm seeing, it's still a very secured job, MUCH lower tuition than dentistry (huge subsidization from feds from pre-doc program all the way to residency),higher pay, more diverse options (specialities and research within these specialities). But of course the things that turned me away were:
1. The Hours - you get paid more but hell you're gonna work for it.
2. The Stress - from long hours/dealing with hospital administration
3. Soooo much paperwork <-- real biggy here, I was bored out of my mind shadowing some physicians when they were hardly talking to patients
Of course a lot of this goes away as you move up the food chain but so does the debt from dental school. I mean, despite them both being medical professions and sometimes half your schooling is the same, post graduation it differs by a lot.
