It's not fixed though. You may think the market for cars only has so much demand, but if you can make a car cheaper, demand goes up. This is one of the most fundamental laws of microeconomics (the non bullshit part of economics.)
There are definitely some zero sum games, I'm not disagreeing with you, just pointing out a nuance. The market for eyeballs/attention is zero sum. Netflix famously thinks of its competition as everything outside of Netflix including "real life."

Is that true or just marketing? Is Netflix seriously competing against every other type of industry? How could it survive if there was nothing but Netflix? Or are they so megalomaniac that they are trying to take over the pharmaceutical industry too? And agriculture? And military? I can't believe.
