Okay. If you want to go that route, I agree. I can't argue with the numbers.
If Hollywood doesn't want to cater to the other races because we have lesser numbers in the Western world, then Hollywood should just focus on white movies 100%. Make movies for them.
Leave the other stories alone. Don't make movies like 47 Ronin (asians) and cast white people. Don't make movies like Troy/Immortals/300 (southern europeans/Mediterranean) and cast white people. Don't make movies like Prince of Persia (arabs) and cast white people. Don't make movies like Exodus/Gods of Egypt (africans) and cast white people. Don't make movies like Dragonball Z (asians) and cast white people. Don't make movies like Avatar: The Last Airbender (asians) and cast white people. If you say you only want to target white consumers, then film stories/legends/folklore about white people and leave the stories involving other races alone. I can live with Marvel not doing Black Panther. What I can't live with is Hollywood saying "nobody wants to see this [black/asian/arab] movie"
then you turn around 6 months later and they're doing that same exact film but, with white faces.
