Isn't it selfish for a woman to abandon her family to pursue a "career"?

I understand if the couple has no kids then it is completely fine if she wants to play business woman. But if there are kids at home it is a mother's duty to tend to the kids and make sure to properly raise them. I see so many selfish women dump the children onto the grandparents, depend on strangers such as nannies or day care centers to raise their own offspring. This is completely unacceptable. I am blessed to have a loving wife who knows her role and puts our family ahead of everything else. Women who neglect their family are selfish and do not deserve to have children in the first place.
