Gotta love lazy identity politics where "group A = good” “group B = greedy blood suckers” and we have simple solutions to everything.
Something like a third of UK pensioners live below the fuel poverty threshold. most of those pensions are not eligible for pension credit/WFA, often due to being pennies or a couple of pounds over the threshold. The demographic most likely to be living in absolute poverty is older, single women.
Your mam got a boob job in the NHS? Really? For non therapeutic reasons? Where and when was this because 40 years ago it was difficult to get even post mastectomy reconstruction on the NHS and the wait list for therapeutic reduction was so long that older women rarely obtained the treatment.
Most of the “advantages” you describe applied disproportionately to men and to small numbers. Roughly 5% went to university, not the 40% currently going. They were disproportionately middle class or aspirational working class and male. Workplace and educational discrimination was widespread against women who were even barred from pension schemes until later in their working lives.
Selling off council houses wasn’t the problem. The problem was the failure to build and maintain a public housing stock for families on lower incomes and developing a half way decent rental model. I’d also say the size of the discount and advertising persuaded low income families to take out mortgages they couldn’t afford (when people talk about this they tend to forget just how many ended up in “privileged” repossession or left with properties in unsellable blocks).
Every generation experiences some crap and some benefits and every generation tends to play down its own advantages whilst playing up those of others.
So lets say we means test WFA to ensure at least the pensioners living in fuel poverty receive it. At that point for a small flat rate benefit its nearly always cheaper to just allocated it (as Osborne found with child benefit). You could offer an opt out/divert on it relatively cheaply for better off pensioners if politically expedient.
Labour needs get well away from the lazy identity based politics of the later 2010s which urban spads and lobbyists love so much and get back to focusing on what individuals need irrespective of their “group".
Slashing WFA was always going to lead to revolt and was directly at odds with Labour’s campaign messaging. Not least because in real world most people know older people struggling or just getting by, unlike MN were everyone over 60 apparently spends 50 weeks of the year on cruises and spends the other two whining at their children over Christmas arrangements.
