Yes, and most people prefer to eat sweets and pizza instead of vegetables.

That doesn't change that single family homes are essentially making childcare and elderly costs skyrocket.

Personally, I'd much rather deal with the inconvenience of having family in my house than pay more than the mortgage on my property for childcare, and have my parents die bankrupt because of long term care costs.

Single family households bleed generational wealth, and that's somewhat ok during a period where the house itself appreciates enough to offset that... but otherwise... it's a bad deal.

Side note... it really helps if you don't hate your family. Sounds like you have personal issues on that front.
