This is true in the entertainment industry, but it's because consumers want to buy what everyone else is buying. Not because there's a huge difference in performance. In fact, it's the opposite. There are many equally attractive/talented performers who can do the job just as well. It's very competitive, success is rare and fleeting even when it does come.
This translates into other parts of the economy. High income households experience high income volatility, consistent with the hypothesis that there is lots of competition at the highest levels of success—not very little competition.
