Yeah, you're right, but we're really only talking about the degree to which it's done. Lying by saying you did something you didn't is cheating. Doing something you wouldn't organically do because you know it's what they are looking for is what every single applicant does, to a greater or lesser degree, and getting inside someone's head to determine their genuine motives is impossible.
What you call gaming the system others call merely playing the game. And I'm not talking about "fluff," which is a polite term for lying. I'm talking about crafting a narrative to appeal to adcoms. Our job as applicants is to make ourselves as attractive as possible to score the A. Their job is to sniff out insincere BS.
To the extent people are insincere and portray themselves as Mother Theresa when they are really a future Beverly Hills plastic surgeon in disguise, all that means is that the adcoms aren't as good as they want to be, and people who are good at playing the game are going to slip through. Is it unethical? I honestly don't think so.
I'm literally spending hundreds of hours engaging in the expected ECs when I'd really rather be hanging out with my friends or playing video games. Does that mean I don't deserve an A because my application is BS? I really think if there was a way to get inside people's heads and only admit people with high GPAs and MCATs AND who would participate in all the ECs med schools look for even if they thought they weren't getting credit for it, med schools would have a ton of open seats, and people who could meet that standard would have their pick of schools.
What about people who manipulate their GPAs by strategically selecting courses and professors, by retroactively electing P/F, by seeking out grade inflating schools, summer classes, CCs, etc.? What about people who take MCAT classes and mask what their natural abilities are without paid help??? JMHO as a fellow premed dutifully playing the game and giving them what they want.
It's TBD whether I'll ultimately be deemed to be full of crap or worthy of a chance to become a doctor. I want to have an interesting, well paid career involving science where I can help people, but, right now, as a college student, yeah, there are things I'd rather be doing than scribing, being a grunt in a research lab, demonstrating my altruism by volunteering, and then writing a bazillion essays about my experiences and how they have shaped me into someone worthy of entry into the club.
