I have the feeling your response just highlights the misconceptions from another angle.
From my personal experience living abroad, we westerners highly overestimate the consumption of our entertainment (movies/shows/music/games) in the non-western world. E.g. log into your favorite western online game in Japan and see what players you end up playing with. Hint: It's basically noone Japanese.
Regarding economy: based on the wikipedia data available here [1] USA+EU+Australia (with GB i think still included in EU there) makes up less than 50% of the global economy, tendency downwards.
