I have a friend who is a nurse. She has a very bright daughter, who sat for a superselective grammar - we don't have ordinary grammars near us. They coached the girl themself, as they couldn't afford a tutor (tutors are very expensive around where we live). She just failed. However, because of where she lives, her daughter then had to go to a "not very good" school.
My friend was quite upset when a consultant at the hospital boasted [as she saw it] to her of how his child had got into said school, and that it had saved him a small fortune in fees. He was obviously very thoughtless, as there was no way my friend can afford the fees. She saw it as the consultant buying a place (through tutoring), when he could have very easily afforded a private school.
However, at the end of the day, everyone has to do what is best for them. After all, we don't make the rules.
(Her daughter is now top at her new school, and being teased for being a swot.)
