One thing I've learned from being in business for nearly 15 years in total, and having had two jobs in management before that, is that women make very good leaders and certainly extremely good managers. Not just any woman, of course, but when you find a good one you make damn sure she doesn't go somewhere else.
Men can be a bit gutsier and probably more creative (generalizing here, obviously ), but the best women just do really solid work, being highly responsible and conscientious, and they tend to take care of their teams in ways that leave us guys in the dust. And that can make a big difference on the bottom line.
I'm not a feminist, and I fucking despise the sick, retarded and frankly disturbing "men and women are the same" ideas that some of my leftist friends are currently trying to ruin their kids with, but I do believe that women should be given more opportunities both in business and politics. I'd probably say that overall my best employees (and also the best boss I ever had myself), were women. The best salesperson I ever had was a guy, but even there I might say the next small handful of spots belong to women. The guys will often have like two spectacular months and then three lousy/half-assed ones, while the women produce more consistently and therefore often end up on top in the end.
Women thoroughly suck at things like comedy and fighting (with some rare exceptions when it comes to fighting), but they can make damn good bosses. Don't underestimate them.
