If females want to stay at home and bring up the kids and take care of the house then they should, if they don't they definitely shouldn't.
Some women are brought up in such a way that they are only able to take care of housework and kids, and i think its a shame to let other potential not be explored, but if that is what they are best at and don't think they could do anything else then so be it.
However, I think there is a part in a lot of males, deep down, which subconsciously expects a woman to be in charge of housework and kids, even if she works more than him. It doesn't mean he won't help out, he'll just leave the overall management to her. He won't automatically take it upon himself as his responsibility to make sure she has enough clean bras in her drawer etc, whereas it is more "normal" for a woman to ensure her family has clean socks. lol. this is a big generalisation but i feel it is common to some extent in a lot of couples.
Personally, I think if i ever had kids, there is no way i'd be taking maternal leave and my partner wouldn't take paternal leave. I'm quite passionate about equal parenting. If his job earned lots more money than mine did and it really would be a problem for him to leave work then I'd be ok staying at home, MAYBE. But in the equally likely chance that my job (i'm going into medicine, so i'd be a doctor) earned more money and mattered to me more than his job mattered to him then i'd definitely expect him to be ok with taking paternal leave and me carrying on working. However this is all hypothetical and i don't think i'd ever have a kid if we were both not ready to give up our careers. And because i can imagine my career being the centre of my life, it's unlikely i will have children.
