Contrary to rest who says women are not empowered in other domains as much, I will say the reason is there is lesser liability for making the accusation. I think, by hollywood you mean actors, and the impact on the career can be big as the job period for a movie is short and does not completely dependent on looks and experience. Other than actors, the majority of hollywood, there are completely different dynamics(make up artist, graphics designer etc.). And for Wall Street it's clear. It's not under the wraps. I think general public sees them as sexist much more than coders.
