To me it sounds like "more people get rich" is a line in the sand. There are more movies to choose from, but the top movies gross more now than they ever have and the "middle-performing" movies, relative to the others, make less than they did 40 years ago. If you draw a line and say "more movies make over 100 million in revenue now than before", that is a natural byproduct of there being more movies to pick from now, and more people watching movies now.

Pareto distribution also explains wealth distribution and "income disparity". There are simply more people now, so the separation between the median and top 1% is going to be greater now than it ever has been. There's nothing political about this. It's a natural manifestation of a Pareto distribution, and as another commenter pointed out: this distribution shows up all over the place in nature.
