I know quite a few children with large bursaries to very desirable London private schools. Without exception they are from families where at least one if not both parents were expensively educated / Oxbridge themselves but now work in relatively poorly paid fields- journalists, authors, artists.
In terms of cultural capital/background there is nothing between those kids and others at their schools apart from the type of holiday they go on.
My school in the eighties did FA for the local community and does little now. For example my kids primary school gets to use their flash theatre for ‘free’. Only it has to pay for the technical support to operate the lights etc. So not free at all.
Finally..... I once very briefly flat shared with a girl who had gone to SPGS and done history of art at Cambridge. She knew for a fact that Big Issue sellers re sold old copies that they found on the tube. All that education for such a lack of thinking.
I would abolish the whole stinking system tomorrow. Watching the jostling for position of some of the families where I live for secondary places has been revolting
