I've got no problem with where a person is brought up as long as it doesn't inform their lack of compassion for people from a different class. I have problems with certain advantages/disadvantages conferred to people in society but not with the people themselves. Coincidentally, I think May's grammar school plan is one of the best plans to improve social mobility as long as there is enough regulation to ensure it is used for that purpose and not abused by parents whose kids already have a socio-economic advantage.
