Before answering this question, I will like to ask some few vital questions, as follows;
1. Who the children school fees and house rent? Men or Women... Men, right?
2. Who provides food for the family?.. Men, right?
3. Who pays for most of the major bills in the family?.. Men, right?
So if all these are been done by men, then how do you expect him to be economical when he has to pay for school fees, house rent, provide food for the family and pay major bills. And that doesn't mean I disagree with the fact, as women are created to be caregiver and home builder/manager.
Things have altered in modern times. Anyone who is more financially secure than the other can provide for the family without any difficulty since it is no longer intended for just one individual. Don't continue to think that men are still primarily responsible for supporting their families because times have changed. Women now contribute to household finances just as much as men do. I've seen families where the woman supports and cares for the family financially even while the father doesn't has the means to do so. It is understanding from both parties.
The men and women have the responsibility to play in a family. If the man can't perform his duties well to provide for the family, the woman can assist her husband in running the family to avoid lapses since the family is meant to be one and they haven't separated.
