There is definitely a deterrent, because there is still an assumption in society that it is women's responsibility to do the caregiving. We know that this is changing with the younger generation, that more and more men are becoming engaged and really want to be spending time with their families and their children, but if you look at the percentage of time, it's still higher for women.
I think women tend to worry more about being in two places at the same time. I talk to women all the time who say, I feel guilty when I'm at work and I feel guilty when I'm at home, because I feel I'm not giving effectively to either one. There's also the notion—and still, even in recent times—that women will be asked about their family responsibilities, members of Parliament or otherwise, and men will not be. There is that media perception still of what women should be doing and what their role should be, and I think this inhibits women.
The other thing that I think inhibits women, and I've heard it many times, is “I don't want my private life put out there”, and so they will step back, and that's unfortunate, because I think it should not be the case.
