Most marriages do not involve two equally-successful professionals, and at least in my case from a purely financial perspective marrying a foreign woman with no real contacts in the US besides me wasn't very advantageous (I should probably clarify that I met my wife abroad because it sounds like I'm talking about a mail-order bride). Nevertheless I think it was worth doing for the tremendously positive effect it's had on my happiness and well-being.

I guess if I had kids I'd have to think about a life insurance policy (I occasionally think about doing that just for my wife).
