> How much do the “good” students help the “bad” students compared to the bad students harming the good students by disrupting classes, bringing violence to the school, or otherwise slowing down learning?

I don't think the parent poster is making a diversity argument here (ie. having "bad" students alongside "good" students enriches the experience for everyone involved). He's more making an argument that a society should engage in redistribution from the "healthy/privileged/lucky/etc" to the "less fortunate ones".

In some cases it is also going to redistribute misfortune as well. Is that fair or desirable?

I'm not sure what gave you the impression that I support putting "bad" students alongside "good" students, which is what I presume you mean by "redistribute misfortune". My last comment is specifically denies this (ie. "having "bad" students alongside "good" students"), and "redistribution" straightforwardly implies redistribution in resources/money.

Giving more money and resources to people who don’t want to take advantage of them in the first place isn’t going to fix the problem.
