DH came form a white FSM family.
His parent, lovely kinly poeple who loved their children put no store by education and expected DH to leave school at 16 and take a job (blue collar), his sister was expected to leave school and marry.
If DH had been born to my parents he would have gone on to university as that is what my parents expected for their children.
It is not only poverty, but poverty of expectation that needs to be addressed.
Nowadays DH's mum is very proud her grand daughter has a degree, although she still does not understand what DH does and says he can't have a proper job as he works in an office.
How one changes this I just don't know, other than DH really values education and wants DD to go to university.
I have a friend who says the only thing that separates working class from middle class is aspiration and the time they devote to getting there.
It also does not help that the ubiquitous "yoof" culture seems to emphasise being cool, hanging out and sending texts and obsessing with appearance, not school work and getting on with life as an adult.
