Aspiration and expectation is everything. Not only do working class kids miss out on the educated role models that are just not there in their every day life, but they also have endless nitwit lefties telling them that certain professions / universities / cultural events are 'elitist' and that they shouldn't aim to do or see those things which the middle classes do. It's wicked, and does more harm to poor kids than lack of money ever would.
Where are these endless nitwit lefties?
I spent the *vast* majority of my working life teaching in areas of socio-economic deprivation, No-one that I am aware of ever told any of my pupils that they couldn't achieve, or take up any career that they wished. And indeed, many of them did eventually go to University. I am the former teacher of doctors, nurses, teachers, chefs, to name just a few and also,unfortunately of more than one convicted drug-dealer.
