Competition is almost the only thing that has ever lowered prices, raised wages, raised quality and invented new things. It's weird to demonise competition.
Yeah under capitalism that’s sometimes true. Otherwise, Cuba has great doctors and great medicine for example. A lot of America’s competition is BS. Companies behaving like cartels is more common.
Companies can start to behave like a government and reduce or eliminate competition, it's true. I don't think it's proportionally a big effect, but happy to read sources.
