My eyes rolled so hard at this, it woke up my wife in the next room. Then we both had a laugh at me being described as 'enlightened' - in my neck of the woods, most people think I'm a troglodyte.
Look, sometimes people do real, obvious, correctable things that result in inequality. There's nothing 'alleged' about these things, and correcting them isn't an 'unendable initiative' - usually, all you've got to do is be a little more self-aware.
A case in point - a startup I co-founded a few years back was all-male for a while, and without getting into the details, we didn't always maintain a sophisticated level of conversation around the office. We didn't change our habits after we hired a couple of female college students part-time.
Later, I found out our part-time employees were uncomfortable with our office banter. Not cool, since this was their first exposure to startups and the type of people that work for them. When I found out about this, my unendable initiative to fix the problem was a quick email, which took care of it. (Still irritated that I didn't pick up on this earlier.)
That's it - no systematic bias in the other direction, no big bureaucratic programs by government authorities, just being aware enough of your surroundings to not be an asshole. You can do it too.
