@autel,
‘The main reason English people use private schools is from social aspirationalism.’
I don’t agree with that. Most of the parents are already successful and socially confident.
As I said, the vast majority do it to get the best possible education for their children. This, sadly, for the vast majority, but not all, means grades.
A vast number, also, have no experience of any other type of school. They move in circles where the question ‘which schools are you thinking about’ implicitly means which private school. They know nothing else and would, frankly, consider they were letting their child down if they were forced to send them to a state school.
Another factor is delegating parenting to the school. It is pretty much true that a good private school will sort hobbies, sports and wrap around care all on the same site. Many parents have no idea what their children’s hobbies or interests are but that is fine, as the school does (that isn’t my idea of great parenting but at least they have delegated it, so it could be worse).
There are some whom my parents would have rather snobbily called ‘nouveaux riches’, who are buying social cachet and a nice accent for their children. As a teacher, these can be really tricky to deal with, as they feel they are buying their children a service in the same way as they might buy a business class ticket, and they are unafraid to criticise any small aspect of it that they feel may not be up to scratch (such as their child not being predicted a particular grade at GCSE!). This is the only set who are socially aspirational and, in my experience, they are a small minority.
