I Got Paid to Improve Rich Kids' Personalities on Their College Applications

I didn't have any "passions" when I was 17. I know few people that did. Instead of mocking "rich kids", why don't we ask why a college should care about our personality or passions. Some people just want to go to school, find a career, start a family and live a normal happy life.
That said, I don't think it's reasonable for colleges to insist that every entering student already be well-formed. After all, acculturation is one of the things that happens (or is supposed to happen) in college.
If you want just a “career” than we should have UBI and socialized healthcare so these people who want to be careerists can go work retail or sell insurance and not take up spaces in our institutions of “higher” learning.
The stereotype you mention is associated with your local large public university for a reason. The more ambitious are seeking a different experience, and the admissions essay is part of the process.
I don't think "personality" rates very high in the interview process; it's really more about legacy, money and other pedigree qualities. They may swear up-and-down about diversity and other feel-good, aspirational virtues, but they're a business bent on exclusivity, first and foremost.
