@GreenLunchBox this. I saw Keir Starmer speaking earlier this year and he was asked about his time at Oxford (where he did his postgrad, he was an undergrad at Leeds). He said it's really odd, full of these really odd people who think that all of the oddness is normal. Said he was glad he had gone to Leeds first as it maybe could have been easy to become 'one of them' and start forgetting what the real world is actually like, even though he was from a WC background and attended a state run grammar, so not from a privileged background at all.
He only spent a year there and had a reference point, but it's easy to see that if you had spent your life at a school like Eton, then gone to Oxford and then straight into finance or something similar, you'd have no experience or view of the real world. What's insane is what a tiny percentage of the country are educated/bought up this way but what an overwhelming amount of them there are in parliament. Normal people are overwhelmingly being represented by people who've got no clue what our lives really look like.
