I have friends who went to Eton and other leading private/boarding schools. Between them they have: children at state schools, cancer, children with disabilities, been made redundant, parents with dementia, been unable to afford a house, become alcoholic, suffered marriage breakdowns, lost family in accidents, voted Labour, worried about the future...
We all have different experiences of life. Who really thinks one life is more 'real' than another? I might vote for David Cameron, I might not. Whatever I vote it will have nothing to do with where any of the party leaders went to school. I'll leave those considerations to all the snobs who can't recognise themselves as such.
