While Eton and its ilk don't have this particular problem, the ongoing suppression of teachers' salaries limits the length of many teachers' careers: in the UK, half of all teachers leave the profession within five years of joining it. There is also a great deal of emphasis on research and its application, at all levels: individual teachers, schools, and regulatory authorities. These two factors create a mind-boggling rate of change in educational practice. It's been just two years since I left the classroom, but in that time, I know that current classroom practice will have changed sufficiently that I can no longer claim any authority on how teachers respond to specific situations. What I can tell you is that any opinion you might have formed about schooling based on your experiences of schooling is no longer relevant. People complaining about not learning how to do their personal finances need to bugger off, because that's now on national curricula, and I know that because I taught that stuff. Boarding schools are well aware of the damage that they once did to their pupils. That's why fagging[0] has been banned, why pastoral care systems have been reformed, why many schools (including Eton) have raised the age at which they admit boarders to thirteen (instead of eleven), and so on.
