>>34104334>elementary financial planYou seem to be trying to plan for future generations. Why would a lazy fujo neet want to do the hard work of having and raising kids, let alone have "attendant responsibilities"? If you want your partner to do good work around the house or just about anywhere, don't go out with a deliberate NEET, especially not a hikki otaku one. They'd sooner lay down, cry depression and expect to be pampered.
Anyway, even if two people who are capable of working get married, it's still safer to have personal, separate bank accounts and both accounts will need an income or at least some funds. Otherwise it'll be difficult to leave if it should come to that.
Sure, a happy marriage is the ideal, but it's not always the reality. My own parent's marriage was more like a hostage situation and I found out that there are quite a few rapists and pedos in my family as well as serial cheaters and druggies on the deep end. My dad was all of that and also a neet who relied on his mum's money, even in his 40s while my mum was a teen who had to rely on his money after her parents disowned her. Even without the abusive shit, I don't think he'd have made for a good parent. Depressed pervert neets shouldn't have kids and I'd recommend not marrying one, including that fujo, unless you think she can overcome the lazy attitude and develop a work ethic. My dad never got there.
Being a witness to certain things that went down made it clear to me that safety should always be part of the equation. People need to be able to leave and some people should leave.
Also, if the bigger earner has a terrible accident and needs support/can't earn money for whatever reason, it's good to have something better than just housework on your resume.
I'd have been literally screwed if my mum hadn't gotten a proper job to support us.
