My grandparents (would be in their 90s now) fought in the wars and did not live extravagant lifestyles. They are irrelevant really as I don’t think that’s who the OP is talking about.
My parents (60s now) did not fight in the war. My Dad had a modest job, always 9-5, not massively stressful, he has no qualifications, my Mum chose not to work and they had 3 kids by the age of 30. We always had a lovely lifestyle, holidays, detached house, 2 cars. That would not be doable today.
They are now retired (before 65) with plenty of money coming in, through private and state pensions. No amazing scrimping or saving or excellent financial planning. It’s just the way it is. They are also now both in poor health due to unhealthy lifestyles mainly and are getting their money’s worth from the NHS.
I live in a small terraced house (in an area that my parents don’t approve of as they have no concept of house prices, they would also never consider a terraced house as it’s too noisy) My husband and I have professional jobs, much more money coming in than my parents would have had but our mortgage is big, bills are big. We waited until 30 to start a family as we couldn’t have brought in our 20s. We will be at least 70 when we retire, that is if we make it that long with what may well happen with healthcare.
I dread to think what lies ahead for my kids generation to be honest.
Yes, I do think younger generations deserve a bit of help with housing now. They will probably work until they die and not have any healthcare in their old age.
