Re older people having "benefited from the best times".
People aged over 85 were born before the NHS and the welfare state. One of DH's grandparents went to the dentist as soon as the NHS came in to get all his teeth taken out replaced by false teeth - because until the NHS he couldn't afford a dentist so his teeth were in a state. He knew lots of others who did the same.
Yes some were wealthy - like in any generation - but loads were in serious poverty. Many started life in pre-WW2 slums. Then they went through WW2. Bombings, rationing (which didn't fully end until the 50s). And the vast majority left school at 14 or 15 to start work (same for "boomers", and actually "Gen X").
As for benefiting from property boom. Some did, yes. Others didn't. Look up Rachman landlords.
And the Centre for Ageing Better's study last year
offers a clear rebuttal of the “wealthy baby boomer” narratives that have become so commonplace in public discourse, fueling intergenerational conflict and resentment towards our older population.
Although it is undeniable that there are wealthy older people, wealth inequality within older age groups is vastly greater than between older and younger age groups.
