I would argue it's the opposite. People on here tend to revere those who come from top schools while not giving time of day to those at other schools. There are about 20,000 new med students each year, which were picked from a group of 50,000 applicants, which was composed of the very few college students who actually kept up a GPA high enough to even keep that dream alive. Of all of those students, about 3000 go to schools that currently have their name on the first page of USNWR, and even of those schools, many on SDN probably would exclude plenty of those students on the grounds of benefiting from a highly ranked state school. There are something like 175 US med schools, each of them able to be very picky with admissions. Most students at a top 50 med school who applied to other graduate schooling (e.g. Law, PhD, PharmD, MBA) with the same stats/resume proportionally (and tailored to that field) would have an acceptance to a top 25 school in any of those fields. Yet you know that most people, even those who know the process well, would have a gut reaction to think of a Cornell law student as more impressive than someone at BU for med school, even though the med school admission is still statistically more difficult.
If anything, SDN suffers from a serious problem with adhering to name-brand value far too much. There are more than a few posters on here who have indicated that they would not have gone to med school had they had to go to a school without name-brand value. Others have indicated that they would try for a different specialty rather than go to a community program or fall out of the elite programs. Then there are the even more ridiculous people who seem to think that going to Brown/Dartmouth is better than say... UVA, just because they have the Ivy undergrad name.
I think I've said this here before, but I do believe that a not insignificant portion of SDN lives and works tirelessly entirely for recognition, whether that be from within their family, their friend group, or the general public. SDN is definitely not anti-elitism. This forum is actually probably one of the primary drivers of institution-based elitism in the US medical world today.
