The main driver for that sort of thing was a system where production of heirs was seen as socially essential; this is now largely obsolete.

(Even then, the really extreme examples of polygamy were more about social status than practical concerns around succession; again, this is now largely obsolete in most societies.)

OT, and maybe, my words ain't effective, but talking to a young woman, i thought i'd talked to "supermom". She told me what she'd "left and quit just to be a good mommy for her daughter." I looked at her, "wearing glasses -too big, to 'be modern'", a warm pullover - knitted, masking upper arms and (her) middle. But than i saw her grabbing a cell-phone (daughter call incomming...), she became 'supermom'.

So if any, could remember that there were 'telephone boxes' ...changing clothes...
