It's bollocks to say that
they have learnt their values from the society in which they grew up
The society in which they grew up offers them MULTIPLE choices about the kind of lifestyle they might pursue. If they went to an ordinary school, that school will have offered them a pathway to Oxbridge if they wanted to take it. I know this because I taught in a school with desperately bad pupil intake, some of whom went to university and one of whom went to Cambridge to study law. Many of the others chose to go to prison instead.
Don't tell me I'm responsible for the bad choices of people to whom better choices are freely available (with a bit of effort)
