Wrong as usual. There’s enough market share of consumers for every business, and it’s not a fixed pie where I can only grow my business by taking it from others. It’s always growing. Rather, competition forces me to innovate so that I make a better product, do it for less cost and provide a better service experience to the consumer, which results in lower costs for everyone.
Cooperation on the other hand, is horrible for consumers because it forbids innovations that make technology better. It also fixes precise so that they can’t be lowered which negatively impacts consumers with artificially high prices and shortages. If automakers cooperated instead of competed we would all have to stand in front of cars to hand crank them. But one car maker decided that was too dangerous after a friend was killed by it, so he invented something drivers have found indispensable today: a key-ignition. It has also created every safety feature like air bags, anti-lock brakes, turn signals, etc.
