I honestly don't think anything needs to be changed regarding the interview process, and I think you guys are taking what I said a little too far! The admissions committee's are in no way trying to segregate to the wealthier people of the the world. It's the final step in a long process of weeding out scrubs. It has to be there. Medical school is something you should have known you wanted to go into for a long time, it's not like traveling around the continental US is something that should have taken you off guard. If it did then you probably did not prepare adequately, which, by the way, doesn't mean you are being discriminated against!
