PrettyBoy, this topic should apply to men and women equally.

This is a topic of financial security and the ability to enjoy certain luxuries and accumulate wealth for the future.
Marriages end in divorce over finances because both the man and women are disastisfied with the economic situation or can't adjust to ups and downs.
To roughly address some other points that you made:
I view marriages as more egalitarian so my household will be run differently than many. Unless one spouse agrees to be a stay-at-home husband/father or wife/mother, both spouses are contributing equally to the finances (even if this is based on % of total income) and to the household (and parenting, if there are children) responsibilities.
It isn't the man's responsibility to provide financially and the woman's to do the household stuff. Unless the couple decides that the man will be the only paid worker and the woman will be the unpaid worker. But in instances where that arrangement has not been made, I don't agree with the "man is the head of the household" thing in the literal sense that most people take it.
