What noone has mentioned yet are multi generational households.
Before we had pensions for all in this country (and is the case in many countries currently), the elders are looked after my family members, often in the same house.
Some grandparents can provide childcare. This is a bonus when most families now need dual incomes to maintain mortgages etc.
Ofc it comes with downsides but with the housing and pensions crises, I see it as being the only solution for many.
Maybe we'll see the rise of more community-style housing, where extended families/neighbourhood groups can help each other out. I kind of hope so. The current nuclear family setup has lots of mental, social, and financial disadvantages.
I don't have family to fall back on so I'm ploughing as much money as I can into my private pension. I think I'll be fucked by the 2050s if I don't.
