its direct consequence of industrialization
>before industrialization population mostly farmers, to work in farms you need strong and large families, having kids incentivized, patriarch provides jobs and takes care of the family
>after industrialization industrialists need workers so they break large rural families into urban working class of small fmailies, but its not enough so they force women into workforce, but its still not enough so they force work culture so everyone takes job over families.
as a result you have absolutely zero incensive to have families. its literally insanely hard work with minor benefits. and its even less so for men cos divorce would literally throw you out of your house onto the streets while your whore wife will tell your kids that dad left them cos he hates them.
