This is a pretty accurate description of where the film industry's at right now, and has been for quite a while.
I can't tell you how many stories I've heard from friends who have struggled to get projects made for very specific, very insane reasons.
Wrong race of the director. Not politically activist enough. Story not about the right groups of people.
There absolutely should be class action discrimination lawsuits, but even attempting to do that is going to get a lot of people blacklisted.
In any case, it's a big reason why most of the new content really sucks.
