I too go with Askme and Amoud...plus in my views, being we humans have insatiable (never ending/satisfying) wants. To make our needs attended; we all required to do hardwork in the maximum possible manner.
But what a woman/mother who could provide love and care to a child, it could not never be compared by father's love and care.

However, we are living in a modern society, where we follow a certain type of life-style (quite demanding and asking to maintain a specific level of standard of living); which is sometime difficult to be provided by one bread earner/spouse in a family, this makes call for another spouse to contribute financially.

Small list of human wants (In general):
1) Professional education to compete the job market or well established business for livelyhood.
2) A good job with handsome package.
3) Career growth with future prospects.
4) A beautiful/handsome partner to care and share.
5) Healthy and smart children.
6) Life without hassles.
7) Over 20-40% of saving for future planning.
8) Good investment either in global share market or in gold, in real estate (Dubai Palm, Doha Pearl or in own country) as post-retirement savings.
blah blah blah....

Now tell me if we have such a huge wish list....
whom you will give first priority.....MONEY OR KIDS....

Obviously kids with MORE MONEY then the option remain open with Mother to decide what is best for HER and HER CHILD....
