"...I suppose that means that domestic relationships are perceived increasingly as undesirable..."
Yes ! And because it starts with the three first years of your life...IF you are a MALE !
You know the time of pee & poo ? And the "battle" with YOUR Mother ?

No wonder it's so "undesirable" (for a Male that kind, yes ?)
