I know the correlations with violent crime in general exist. We should still check the correlation for sexual assault in particular, because I don't know how different it may be from crime in general.

Playing devil's advocate, we assume here that some sexual assault is driven by feelings of entitlement, and rich, powerful, intelligent males tend to feel more entitled than average (and society supports those feelings in them). The powerful boss sexually assaulting his female secretary is practically a stereotype.
