Hollywood IMO is a microcosm of the intersection of exploitation by the rich with toxic populism. There are more problems with regards to kinds of representation than even fit in one topic, but the involvement of women - both as subject as well as creators - is a great place to start.
From a solutions perspective, I grew up with people celebrating the democratization and decentralization of media, so maybe it is natural for me to see answers in avoiding mass/broadcast/mainstream media in favor of egalitarian DIY efforts. Modern creation and distribution technologies mean that (unlike fifty years ago) struggling to get others to represent you is not the most obvious or realistic option. If movies are a "popular" art form, then why not popularize them as a medium for women to independently make their own movies?
What I don't understand is the decision-making of people who would rather stick with Hollywood instead of going independent. Lots of creators still flock there, despite knowing how shitty it is. It seems to be a catch-22 problem of "mindshare", where people who rely upon industrial mass-media are more likely to only see that as valid. But I don't get why those who have the choice to DIY or try changing the values and practices of an uncreative, incestuous, exploitive cartel from within would choose the latter route. It sounds a lot less empowering. But many still do.
Consider the ways that punk and the indie music scene did so much to decentralize the "music industry" and increase representation of what women's music and who woman musicians could be. By making it yourself, networking your own distribution and venues. Something analogous needs to happen with video/movies - and not by relying upon a giant corporate gatekeeper like YouTube.
