American system feels more unfair when you're given points for extracurriculars like playing instruments or sports, like that's not going to hold poorer children even more (also how's that related to academic performance at all? Unis should not care about unrelated things)
I probably agree with that, but also acknowledge there's no good way to make that completely objective.
Even worse, rich kids have far more means to engage in extracurriculars than poor kids.
US universities do care about extracurriculars and GPA and other things because they aren’t optimizing for raw academic performance, they’re optimizing for various other things like an interesting student body (that attracts donors, professors, and future students), real-world networks, and so on.
I would expect wealthy to always be well represented.
It's easy to think this but its not true. There is just a ton of privilege involved in life. There are groups in India who purely tutor slum kids to the top IITs(the JEE exams in India are very hard).
