The solution is to make gift classes fluid. That is, the worst performing kids leave the program every year, while the best kids outside the program move in. Parents can only push so much, but they can't change talent distribution.

What about the kids who thrive when their parents push hard enough? Well, in that case the kids are indeed talented, no? If the US people are inspired by seeing the street of LA at 4:00am or by some NBA dude practices free throw 4000 times a day, then we've got to admit that toiling also works and should be admired in academic training.

Stack ranking kids sounds terrible.
