I agree with @FemmeNatal tbh...
It is the norm for a substantial large section to get money from your parents, free rent etc -to save....
I grew up in the south. Went to local Comp , mostly a lower middle class/working class area. Not rich, but mostly home owner area, bought council house.
And EVERYONE I know who bought property has had some leg up/ help with deposit- because their parents although not rolling in it- were able to help them. Letting them live rent free, inheritance from grandparents, generous loan etc....
It's like a dirty secret....
I understand that their are many people who do not have that privilege.
Born into family who rent, will not inherit, who do not have the space.
It doesn't mean that people can't strive to be richer- but really not everyone can be rich...
It's just how the economy works. It's certainly not about hard work.
Some of the laziest people I've ever met, are also the richest.
Some people do not have the skills, personality, confidence to start a successful business.
Many people do not have the academic ability to strive for a well paid profession.
Tbh lots of people do strive to live in a council house, which is completely sensible - as it is a secure tenure that can get you out of the poverty trap due to low rents. Living in private rental can be insecure and very expensive.
