> Charter schools kicking out problematic students isn't some loophole, it's the main point, and it absolutely can improve the education for those that remain.
I'm provisionally accepting this as true, partly because there's some truth in it and partly because I think it leads to an interesting discussion. This is great for the remaining students at the charter school.
That problem student goes somewhere, though. That problematic student still exist. They are now in another class, with other students. Some of those students are problematic and some are not, but per your premise -- that other class is now worse than it was. You haven't improved anything, you've just taken a disadvantage from one place and given it to another.
One might consider a scenario where this happens repeatedly, and you just get a class full of problematic kids. Those kids don't learn anything, but at least the non-problematic kids do.
There are several problems with that scenario, but one such problem is independent of ethical concerns: You just aren't going to find the people to run that school or teach that class for the amount society is willing to pay. Schools for behaviorally problematic students exist. They tend to be private, expensive, and full. They also tend to focus on students who e.g. assault other students in the middle of class, rather than on students who e.g. won't stop talking in class even if repeatedly removed from class, or even students with out-of-school criminal records.
