A slight digression, I've been listening to some adults say in their 20's with a negative view of their chances of owning, I.e mortgage, of their own home. Some are anti baby boomers for having investment properties and material items.
Case 1. A friend had a GF 10 years ago when they were 22yo. Both expressed a desire for many kids. The guy however likes 4x4 cars and spent much money on them. Fast forward 10 years and they have 5 sons the latest baby born 8 weeks ago. The guy still spends money on cars and they've survived financially on one wage. Yes he whines about not being able to buy their own home. BTW he's a high school teacher.
Case 2, friend 26yo has only had cashier work part time. Whines that she'll never be able to buy her own home. Doesn't have a BF and is fit and healthy. I suggested she join the armed forces- adult wages, cheap meals and board, free dental, medical, travel , eventual home loan etc. Her reply "but I'll miss my friends".
At 17 years znd 4 days I joined the RAAF. At 20yo I was discharged and had qualified for a defence force home loan (now 6+ years). At 29yo I utilised that loan to buy our first home. From there on I sold when prices were high and purchased opposite. Also 12 hour shift work for many years sometimes 6 days a week.
In life you have to create opportunities, sacrifice and work hard. Some suggest inheritance helps, yes it does but most people benefit after 55yo with that.
Then there is the flip side you mentioned and society is based on 2 incomes now to achieve what one income gave pre 1980. It is indeed a good discussion but my friend that has only ever worked part time...might have her friends but that isn't much of a plan and planning is essential.
I hope I've explained it OK.
