Cuts, that might be my favorite post you've ever written!
Along the lines of the original question, I've always wondered if specialty choice correlates with the socioeconomic background of the medical students? In my original medical school class, most of the wealthy medical students (e.g. the ones driving Porsches to 1st year classes) sought out more lucrative specialties, while students from more middle class backgrounds went into family, medicine, peds etc...
Certainly the medical school class is skewed to people from higher income families, but relatively speaking....where would everyone place rads applicants?
Based on my N=1 experience so far, I would guess most students are coming from more upper class backgrounds compared to their classmates.
