I don't even see the correlation tho.. there's a big diff between a married couple who are both working, having a joint bank account than a young couple "in love" where 1 person is making 100% of the income..off of porn.
Yup. There can be a big difference.
Though there does not have to be. For me, regardless of who is working outside the home, and who is managing things at home is immaterial. You committed to sharing a life together, that includes sharing of tasks. Doesn't make a lot of difference who is making the money. Be equal partners, have equal shares.
Again, that's just what works for me. Everyone has their own system.
