Because women tend to be afraid of loss and prefer more definite things like saving and buying jewelry as their investment, from most of what I see like that, it is different from men who risk themselves at great risks in their lives so men have a great leadership spirit and are more realistic than women in living life.
Men more realistic? No, I don't think so. It's often women who manage the family budget, but also the administrative documents (I'm thinking, for example, of registering children for school, a sports club, etc.).
As soon as there are children, the notion of family changes (obviously) and budgetary responsibilities too. Women are realistic because when they are mothers, they want above all for their children to have enough to eat and good living conditions in general. They can give up past personal pleasures for their children (like buying clothes or other things). Perhaps women have more of a sense of sacrifice for their children.
I don't see any point about women is not realistic. I believe he use a wrong word to construct a sentences since I believe that's not how women act on such situation.
But rather I believe that women is more careful dealing with finances especially on budgeting. Since usually men are risk takers which they usually came to the point that they are not careful on spending's and want to get everything what they want especially taking huge risk for investment and other matters.
While female are always in conservative sides and always choose what is best for them and for their family.
