I think there are too many goys in Hollywood...
Boychick, the reason that Hollywood is so "Jewish," is because the movie industry was originally, as silent films, in New Jersey. The move to Hollywood reflected the needed bright sunshine for an imperfect new technology. And, oh yes, new technologies could get someone to lose their shirt, so to speak, in the original investment. Guess who was allowed to try their luck in the new technology? You've got it. Jews. So, since the technology was perfected, and the masses enjoyed the entertainment, Jews were the proverbial early birds, and then built the industry (like the garment trade was built by them in NYC).
It is all a matter of the early bird catches the worm. That's why steel, shipping, automobiles, military systems, etc., are known to be industries dominated by Gentiles. They were the early birds for those industries, and being a surer bet for one's investment, they got to "invest" in the industries when they were smaller.
Let's not begrudge Jews for them entertaining the masses for the very difficult 20th century. I'm sure Gentiles will take over Hollywood in time; just like Christianity. Get it?
