It’s a private school. I don’t understand the issue.
I challenge you to name a perfect system in the universe that was created by a human. Just because perfection doesn't truly exist doesn't mean we shouldn't strive for it anyway. Or else what's the point in even being here?
Also, I totally reject this on the basis that education is a public service that allows economic mobility - restricting it to the rich, whether in a public or private setting - is immoral.
So because you have to pay for something, only the rich will afford it? Just like only the rich surf the internet, because AT&T charges a subscription?
