Some (obviously generalised) traditional white working class values:
The elevation of manual work over mental work, so a hod carrier who can heft a huge number of bricks onto his shoulder is working harder, and is thus more respected, than the "pen-pusher" boss in the office, whose arm presumably barely has the strength to pick up a pen.
The non-acceptance of gate-keeping measures like Maths GCSE. I have not used manual long division, much less solved a quadratic equation, since I left school, despite me now working in IT. The middle classes accept that Maths GCSE is a proxy for an IQ test and is a door-opener. Lower class people are correct in their assessment that the stuff taught in Maths is nearly all useless and irrelevant to work, and they don't see or don't accept the gate-keeping aspect.
The elevation of the community over the individual. If you are starting to do well and are from a working class background, you are 'getting above yourself'. Someone who stays in the area and joins in the local culture is valued above someone who leaves for individualistic reasons.
Economic responses to situations are often communal, e.g. an older relative getting a job for a school leaver in the place they work, or families lending each other money and pooling resources. When you have an extended family and community, you have an economic cushion and you don't give it up lightly.
Most people outside of white English culture have very little idea of how much the class division pervades everything. It is everywhere, but mostly invisible to outsiders, and the effects are all-pervasive.
Take the idea of 'respecting authority'. A white working class boy will often accept a working class authority figure, but not a middle class one. And the class origin of a person is 100% obvious as soon as they speak or eat.
On the subject of white working class 'entitlement', these boys have grandfathers who chant "two world wars and one world cup", and parents who remember their grandfathers waxing lyrical about how Britain ruled the world. The legacy of being poor in a post-colonial country runs very deep.
