Disagreeable personalities tend to get paid more. When a man is disagreeable, people usually get wide eyed, but then accept him as kind of abrasive, but lovable. Women are either less likely to be disagreeable personalities, or less liked when doing so.

If women get paid less, why doesn't google hire only women to save money?

Disagreeable people also tend to get fired more, in my experience. Perhaps it balances out, which would explain why there are still disagreeable people.
