Women are not Economical than men. In my own experience, when I and my sister were in the higher institution. Money given to us for our up keep monthly hers was always higher than mine, but before the months runs out she always complain to be broke first.
Men are more economical because he manages himself,wife and kids sometimes even parents and siblings, the difference is clear how can you compare a woman whom is also managed by a man. The finance of a man belongs to him and his family, why the woman own belongs to her alone.
Statistically, go to any home of a man and woman and check their closet's you find more of expensive bags, shoes,hairs, makeups,clothes, jewellery etc in a woman closet than that of a man.
Men spends more on family which includes wife and kid's, that doesn't mean he's not Economical it even makes him more economical on how to meet up the needs and wants of the family. Women are gifted with the ability to manage the affairs of the home including money for upkeep but that doesn't make a woman more economical than a man.
Although some men can spend extravagantly on cars, clubbing,bars, vacations, on women etc, but it depends on his income. Women spends more on fancy stuff's like jewellery, hand bags, shoes clothes, make-up, women hair etc.
The actual fact, is that men spend more than women because men has more financial obligations to cover than a woman. So it makes him more financially economical in other to cover those obligations which women are also included.
