In my post referred to by GSM are three things which I believe enable someone from a "working-class" family to make the most of him/herself, They are health, education and confidence.
Clearly GSM had plenty of the last, when she set off to train for a profession which would give her job satisfaction and a quality of life she would not have enjoyed otherwise. Not all those living in a rundown housing estate are so lucky. Perhaps they come from a family who are unable to get employment and have no savings, for whatever reason, and their schoolfriends have no plans beyond "the dole" and gathering in a gang to ogle girls and repel rival gangs on their territory.
A child in those circumstances will have no confidence in his/her ability to do anything more challenging, more interesting only to follow in their parents' footsteps. A minority find confidence in a grim determination not to go under in the tide of apathy - but most will drown.
But suppose that child likes to draw cartoon characters, or to invent dramatic stories, or play tunes on a guitar, or to make scraps of wood into toys, or care for animals. These qualities may never be skilled enough to take them into careers where they will have enough spare cash to develop a lifestyle where they own a Merc and a big house in the Home Counties, (even hitting the bigtime in the entertainment and art worlds takes luck as well as talent) but if the skills are nurtured they will still have them as adults. They will be using them for the benefit of the people they look after. - and for their own mental well-being, keeping them from needing medical attention.
Society is wider than just the intellectual professions.
A long time ago, a small group of teenagers from a deprived locale who, basically, did little more than 'hang' with each other in groups and irritate the neighbours and residents, were given the opportunity of hearing and watching one of Mozart's operas (forget which one) - as part of an 'experiment'.
Some had absolutely no interest whatsoever (and didn't even know who Mozart was anyway), but a handful were 'game' for the event.
Cut to the chase - they were all interviewed afterward. I particularly remember one youth, in his trackies, trainers and hoodie, who said (something like) "that was amazing, I never knew music like that existed. Another was "blown away".
My point - which is not that we should introduce teenagers to Mozart - but that some of these youth have, because of their family environment, background, etc - a very limited horizon.
Perhaps if they were more 'aware' of the wider world and its opportunities, the possibility of travel (for the sake of travel, not a week in the Costa-del-whatever), the Arts, too - they would aim a little higher than the dole, a low-waged job, county lines, etc?
... and, in fact, I think it's a shame that they were not aware of Mozart, in fact. Man does not live by bread alone.
