It's not as much about the white masses as it is about the white, affluent people in power in Hollywood and in the rest of the US entertainment industry (which is still the overwhelmingly dominant entertainment industry in the world).
They're the ones that make most of the decisions, and are responsible for what the masses see. They're also the ones who give themselves awards and pat each other on the back at the Oscars:
"In 2012, the results of a study conducted by the Los Angeles Times were published describing the demographic breakdown of approximately 88% of AMPAS' voting membership. Of the 5,100+ active voters confirmed, 94% were Caucasian, 77% were male, and 54% were found to be over the age of 60."[1]
We know this argument is incorrect to an extent because at least for the top-tier films their world-wide collections overshadow the US collections.
US itself is not as white as it used to be, and when you add world-wide audience its more mixed.
You could have made your point by not stereo-typing.
