I have another guess: Rising inequalities in the U.S. means fewer and fewer people can have access to high quality movies. This means the internal market, which is the fuel of Hollywood, is dying and that's why Hollywood is dying.
It's just an intuition and a guess.
EDIT: Also, it could mean that the concentration of money inside a few hands in Hollywood mean they try to make fewer movies so they get more return on investment. For example, if you produce 20 movies per month or 10 movies per month, and you have a monopoly, then it's cheaper and almost as profitable to 10 movies a month. Only an healthy competition or subsidies like in France can make you want to produce more movies.
