It's illustrative to consider an example: working and middle class Asians. It's almost a truism at this point that, while they're good at getting good educations and jobs, they almost inevitably end up hitting a wall ("the bamboo ceiling"). And it's almost as if it's by design. Society told Asian kids that they have to study and get good grades to get ahead, so they did. Too well! So the rules changed, and then they had to have extracurriculars. And they did that too! Piano, Academic Decathlon, tutoring, tennis, violin... they aimed for what were seemingly all the good extracurriculars and excelled in them. But then certain gate keepers were like, "whoah, way too many Asians are getting in. Gotta change the rules again!" And so that kid with a perfect GPA, great test scores, even some research experience, and on top of that does pretty well in both cross country and piano (albeit not nationally ranked) gets kicked to the curb because he's too "cookie cutter." The new criteria are "extracurriculars, but make sure to do something that makes you stand out and be super unique!"
So now that's the new publicly-stated resume to optimize for. The right activity to do, as it turns out, is "do whatever only the already-elite have the resources to do." Elite gatekeepers have a set of signifiers for entrance into the upper class for one and one reason only: to keep out riff-raff like you. Any entry criteria that would change the cultural and literal complexion of the upper class too much is, ipso facto, a bad criteria for entry.
And consider the best case scenario: you do get in. But even then, you're still an outsider. Hell, you didn't even go to Andover or Exeter! And you didn't even travel internationally for the first time until you went to college? Back to the fields with you, peasant!
For most people, aiming for professional, middle-class jobs seems the most realistic goal to aim for. Ain't a bad lifestyle at all, if you can accept it's silly to try to win a game that's designed to make you lose.
