I’d take Rayner as more about not being ashamed to be working class.
I heard an interesting comment the other day with regards to the US election - it was effectively “if you are middle class and can only really afford a $30 political donation…” - that’s not middle class. That’s Americans calling everyone middle class because the idea of being working class is considered shameful to some. If you can only spare €30 as a political donation then you are closer to the breadline than “middle class”. Note I’m saying “afford that donation”. Not whether they want to of consider it worthwhile / a priority
I can’t really get into the second paragraph now because I’m supposed to be paying attention elsewhere. Suffice to say we are unlikely to agree here and probably are not in alignment on the definition of “wealthy”. And like “working their tits off” (which many do and don’t end up anything close to wealthy - something that always comes up in the private school tuition discussion)
Of course lots of people work their tits off and don't become wealthy, but I'd suggest that people who become CEOs of companies and are wealthy as a result, have worked bloody hard to get there. I can barely think of any off the top of my head that haven't (and many of whom have been from a working class upbringing).
I don't think there's any shame attached to being working class in the UK now, as I say there's almost a pride to it, and it's seen as being more 'real' as being middle class, which is a bit weird.
