A kid does not have the right to another kid’s education by forcing him to attend the same school and act as his crutch. If you believe they do, you should march down the the nearest hospital and offer up a kidney, a lung, and a lobe of your liver, because that’s what your theory of justice leads to.

>The system is broken because smarter kids or kids who come from more educated families are escaping it.

Yeah, no. Do you have any experience with the public school systems in the US, or are you just viewing this from Europe and engaging in some vigorous armchair analysis? The problems are manifold, and they're exacerbated by the fact that the school system is not nationally funded, but locally by local property taxes, so impoverished areas with stressed parents also get poorly funded schools.

I know some people who took part in Teach for America, and part of that experience was that they taught in some of the lowest performing schools. And one of their big takeaways was that the teachers in those classes couldn't maintain basic order, let alone teach effectively. Smart, well behaved kids aren't going to improve that situation, and it's going to seriously hamper their ability to get a good education if the teacher has to focus on keeping people in their seats instead of teaching.

Smart kids just get held back in school

It's clear to me that A) you don't have kids and don't have any experience with kids in school B) you led a very privileged life and had a better than average experience in school C) think smart kids should be held back or slowed down so the less fortunate kids can keep up and further dumb down and brain drain society because that's how it works in schools D) You're so ignorant on the subject you obviously are a victim of the public education system you're so adamant to defend.

Your analogy isn't worth addressing, its not even close to accurate. Its pointless to continue.
