I'd have to agree with a lot of the posters. I'm a white male and my female friends are FAR more concerned in general with finances and investing than my male friends. It doesn't surprise me that the majority of posters here are women. In general, our society pushes a lot of family responsibility and planning onto women whereas men mistakenly value a more carefree attitude - living in the present, instant gratification, and you can start planning when you settle down.
I think it's more systemic and it's something that society desperately needs to address. I don't know if it's men losing their traditional 'provider' role in the family as society changes, lack of father figures during childhood, the education system gearing itself more toward how girls learn and away from boys, or the decline in traditional male fields of employment like mining, manufacturing, etc.
