"So many people agreeing it’s ok, but so many with the caveat “as long as they’re saving for a house deposit”. So if they’re not then it’s not ok? Surely people can make their own choices how to live their lives if it’s not impacting on anyone else outside the family? If the family themselves are happy what’s the issue, irrespective of the reasons."
Excellent point.
"During lockdown I’ve had time to read more about different cultures (currently reading a book about an amazon tribe) watch documentaries etc. Even shows like tiny house nation and a very interesting Chinese home makeover show! (families of 3 generations living in tiny spaces)."
What's Chinese programme and where do you watch it. It sounds interesting .

"I grew up in Singapore and lived in a 3 generation household growing up."
"I do have aunts who lack a pension who are renting out their homes and living with children - in this country, they would have gone on benefits instead but in singapore, they are not entitled to claim anything."
About 25 years ago I lived and worked in Singapore. I had to pay my CPF (Central Provident Fund, if I remember correctly). This meant over a couple of years I accrued a massive fund which I was allowe to take when I left. Such a good idea. Had I stayed that money would have been used to care for me in my old age. I wish we had it here.
