Either you have rich grand/great-grandparents or we come from VERY different places. My family has been historically poor up until my dad, who is just middle class now. Both sides of my family have struggled until death. I don't know of anyone other than maybe one or two who had parents growing up that had "built a life of their own," then married and started a family in their very late 20s.

Historically I come from a family of peasants. Especially after WW2 both sides of my family were poor, but there was a period before then that one side was rich farmers.

They were only rich because my great grandfather bought the farm where he used to work as essentially slave labor (they'd only get food and board in return for being manual labourers, it was a thing back then).

But anyway, this age thing was something I read in books about late 19th and very early 20th century.
