Discrimination still exists on a massive scale.
I have one friend in Brussels who is one of the top researchers in her own special area of social policy in the European Commission, which sets policy right across europe.
She is the best qualified person in her department (otherwise all male), and has a higher output than her collegues, and does the same job as them. She gets 33% less pay cos she's female.
I've told her to complain about this, but she's too much of a wallflower to do this. I've told her to leave, join a different company, but her field is so specialised that basically, there is one good company that does it, with all the contracts, and she's already there. She won't go independent either, I gather its not really possible in her field.
I see other examples of discrimination all the time - one university I studied at is the University of East London, which is rooted in a black community, where the vast majority of students are black, yet the professors and lecturers are overwhelmingly white and male.
Look at the UK parliament and the US Congress / Senate - overwhelmingly male.
As said above, a gathering of the powerful tends to reinforce that power, and a gathering of these with less power, that excludes the powerful, is often seen as a threat to that power.
