That's where things fall down, though. I've done some admissions work (I am not professionally in admissions or HR or anything, I was just an academic mathematician). A lot of "qualifications" are experiences you can buy. You can buy volunteer experiences here or there, whether as literally as flying your child to Africa to volunteer or as simply as not asking your kid to contribute to paying the rent and letting them tutor for no cash. You can buy your kid test prep classes -- yes, the poor kid can get an SAT prep book from the library but the rich kid can have a tutor take their child by the hand and cajole/harass/massage the kid through test prep. You must pay pay pay to have your kid participate in traveling soccer league, dance team, lacrosse, etc. Remember travel soccer and similar activities are a way of divesting from the public schools, ensuring that this money and coaching benefits kids whose parents can pay (the right kinds of kids, the kids you want your kid to marry). What else? The music lessons, the robotics contests, the school district that has a full suite of AP or IB classes rather than just a couple, but in which houses start at $425k...
I sure as shit am buying qualifications for my kid, fully recognizing my role in participating in this flawed system. Kid's in robotics, language classes, gets to travel. We switched the kid's school to go to a school with higher standards. We teach the kid both reading (100 Easy Lessons...) and writing (workbooks from the non-US country with better public education) -- small expenses in $ but nevertheless expenses. I'm sure someone will happily tell me that the last part is just good morals on my part, or something, but you can't tell me that $100/day for a robotics summer camp is just good morals. I am buying that kid qualifications.
And then someone will tell me that's not race-based, but look at the perpetuation of wealth disparity thru US history, from chattel slavery on through the robbery from the Freedmen's Bank to the riot that burned down Black Wall Street to the fact that Black servicemen couldn't get mortgage assistance or GI Bill college assistance after WW2. Follow the money.
