Uniforms in school don’t wipe distinctions, they make them less visible to outsiders, every kid still knows who is rich, who is poor, who is religious and who is not. Uniforms serve as a security theater, and limit considerably the freedom of every child who wears one while augmenting the parents expectations of how safe a place the school is.

That could be true, but I think only if there’s a systemic effort to diagnose and put those children into specialized establishments. Where I’m from, it doesn’t appear to be the case.
