You aren't getting funding for the "Eat the Rich and Fuck Imperialism" movie, and if you do get funding, the studios will lock you out, and if you do manage to trick a studio into publishing a movie that works against the interests of the rich investors who own everything, your movie will struggle to get distribution, and even if you manage to jump all those hoops, your movie will be ignored by the critics until they HAVE to respond, and then they'll trash it
It's called "the propaganda model."
