> And why exactly is it the man's responsibility to provide financial security for the woman? I'm sure for most women it's not that it is the man's responsibility to provide financial security, but that the man is going to work with you to be financially secure rather than against. If you've spent your twenties working hard and saving, you probably don't want to marry someone who's spent their twenties running up a credit card bill. You very likely will spend your life together arguing. Not that a diamond ring is necessarily the best way to demonstrate financial responsibility.
