Which isn't true, and never was. I get why we do that with kids in Reception and Year 1. With young adults, like University students, the fact of inequality of potentials of individuals, is just a fact anyone has to live with.
I am clever, but I am a fat, average looking guy. So that's what I have to live with. David Beckham is not so smart, but he is sporty and looks great. He uses his innate talents, and I use mines. Nobody is discriminated by being different.
The system has been built by those with means. And those with means more often than not are clever, hard-working people. That's how you get successful in the first place. And when you are born with great talents, you will go up too. That was the point of aristocrats being replaced by bourgeois, and now people in tech growing no matter where they are from.
