That's what these discussions are for: to discover solutions and obstacles.
Have you ever heard of the monkeys and ladder metaphor?
Things need to change. It's great to be skeptical, but not if you're not also optimistic at the same time.
Monopolies are bad for many reasons, not just because arbitrary "rules" or whatever you think is easily dismissed, but because of the opportunity costs that even the owner of the profits incurs. We're not talking about money or status or power, but actual meaningful change of the total composition of their culture & society and the world. They are literally preventing themselves from experiencing a world that gives them everything they can't have now and clamor and hurt themselves chasing after. It's the ultimate irony.
So yes, you should have hope. There is NOT a "good" reason for being a greedy parasite. People have just forgotten and/or been manipulated into believing in fake power. This false faith (fear) is literally what enables these fake leaders like Jeff Bozos the clown to succeed.
Please next time contribute more to the conversation than just whine.
