I know there are some comments here about bad attitude but I will give the OP the benefit of the doubt. Keep in mind, this is someone who just got fired and that can provoke a variety of motional reactions.
I am with you on this, I do not know why women would choose this instead of raising a family. Men often reach a point (call it mid-life crisis) where we feel like we have not made an impact, we may question whether or not we made the right choice here or there. A woman that would choose to stay home and raise her children can have in her a sense of satisfaction knowing that she has made a positive impact on other people's lives, the lives of her husband and children. Each of us has a vocation, a role in life, and when we line up our actions to achieve the purpose or vocation you get a sense of peace from it. What I read from your post is that this job, or the whole concept of working for a corporation has robbed you of your peace.
