The douchebags <-> inequality connection goes both ways.
Extreme inequality produces douchebags because it enhances the importance of authority and favors promotion of those who'll uphold arbitrary authority (in order to enjoy a powerless but privileged status, hence the connection between the douchebag and what is sometimes called "white privilege") over those with actual talent.
That said, those douchebags are promoted for a reason, which is their usefulness as stewards of an unfair, failing society who'll keep the secrets of the shit running it. This keeps them in power and enhances social inequality.
