> until we collectively redefine and enforce a value system that benefits us allHere's the problem: you can't.
First, people have disagreements, often very fundamental ones, over what "benefits us all". There's no way to resolve many such disagreements short of brute force.
Second, "enforce"--note the last five letters of that word--means some people are given the power to do things to other people that, if anyone else did them, would be crimes. Throw you in jail, fine you, restrict the things you can do. Indeed, that's how David Friedman, whose "The Machinery of Freedom" is worth reading, defines a government. And the problem is that government still has to be done by humans, and humans can't be trusted with the power to do such things.
Ultimately the only defense we have is to not give other people such power. Not governments, not tech giants, nobody. But that requires a degree of foresight that most people don't have, or don't want to take the time to exercise, particularly not if something juicy is in front of them. How many people back when Facebook first started would have been willing to simply not use it--because they foresaw that in a couple of decades, Facebook would become a huge monster that nobody knows how to rein in? If my own personal circle is any guide, the answer is "not enough to matter"--of all the people I know, I am the only one who does not use Facebook and never has. And even I didn't refuse to use it back when it first started because I saw what things would be like today--I just had an instinctive reaction against it and listened to that reaction, and then watched the trainwreck slowly develop over the years since.
So we're stuck. Even if we end up deciding that, for example, the government will break up the tech giants, slap huge fines on Zuckerberg, Bezos, etc., maybe confiscate a bunch of their property, maybe even make them do a bunch of community service, possibly even some of them serve some jail time--it will still be just other humans doing things to them that no humans can be trusted to do. It won't fix the root problem. It will just kick the can down the road a little longer.
