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.
