Rich families only hire tutors if their kids need extra help in a subject. The belief that all rich kids have tutors for everything is completely absurd. Further, the claim that you can devalue the good test scores of all rich (white) kids on the completely made up claim that they must have had a tutor if they did well is purely classist and racist.

You have clearly been manipulated into believing a left wing narrative about education that is not real. You have watched too many documentaries on people who cheat the system and then extrapolated that to everyone according to your otherwise racist world view.

A tutor can not turn a stupid kid into a savant. They can not get an 80 IQ kid to understand geometry, statistics, chemistry, etc.

If a kid gets a high test score it is because they earned it. It is because they understand the material. And because they can do the work, and they are already up to speed with what they need to be they are qualified to go to an institution that has a fast pace curriculum. It does not matter if they learned it with or without a tutor. They still did the work and learned.

Similarly it does not matter if a kid who can not score well on the test could have got a decent score in the hypothetical situation that they had infinite access to tutors and money. They got the score that reflects their current, real world abilities. If they are injected into a demanding school through well meaning but stupid people they will only take a seat away from someone who deserves it more and who can succeed in it, only to flunk out.
