Bigger families provide support in all sorts of ways, either financially or if you need babysitting, you got someone who is glad to help. Multigenerational homes are financially most sustainable solution for all of us. But if you're in America and still live with your family instead of paying overpriced rent, society treats you like a loser. In my country, more often than not, whenever there's a major thing in your life, relatives are the first to help. My mom was fighting ALS for years and if we didn't help family to help us, she'd be dead a long time ago. Unhappy marriages are often caused by a lack of real life-threatening problems. If you needed someone to change your diapers because you can't, you'd reconsider. Trust me. Even if my dad were a cheating asshole, he didn't have time since he was our lifeboat, literally.
