I'm basically advocating for a "prenuptual contract" culture, I guess, rather than reliance on family law. Happier marriages often naturally settle into this sort of thing, over time, but making it tradition is more effective across the population.
Away from lavish weddings, McMansions, and megadiamonds, toward sensible financial planning and addressing common concerns in advance, with the help of advisors and templates.
People think this is tawdry, since we're supposed to be romantic and trusting, but I see it as prudent and sensible. And a solid financial foundation gives romance more room to bloom.
