Parents are no longer raised in their own children and those children are encouraged to discern themselves from the family

I would say culture and economics play a massive part

Also having children in the short term is a massive hit to people's lifestyle it's worth in the long term but you have to pay a lot in the short

People don't like delaying pleasure and enjoyment

Also if you have children in later in life you kind of find reasons to exist that don't involve having a family

Also people get set in their ways as they get older making it harder to start a family

Also people start families too late in life

For me I would most likely be in my 30s when I start having kids making me in my 50s or 60s by the time they leave home

Know I think if I could I would have prefer to have started having a family in my yearly twenties and then be finish with child care responsibility in my mid 40s
