As head of the household, I think the man has the responsibility to make final decisions. However, based on the questions, we should look at the age group that we are talking about. Women today, such as the beautiful women of Alpha Kappa Alpha, are apt to make as much if not more money than their counterpart. I saw couples should have a household - to purchase things for the house but one should also maintain individual saving, joint saving and individual checking checking accounts. As a man I plan to be a provider but that does not mean that wify can't also pay bills. Also, I don't like this 50/50 stuff. Marriage is not 50/50 - one will always give more than the other just like one will make more than the other. The key is to work jointly to acquire, save and thus have a complete life.
