I certainly don't mean to imply that misogyny (which those kind of attitudes are a specific expression of) begins in the workplace. It's just where I currently am in life and where it has been most apparent to me in the past several years. I agree that it starts much earlier and there is significant work to be done at that level as well.

I'm not sure misogyny is the only possible explanation here, and I am almost certain it doesn't account for the entire gap.
