Capitalism is a game where only a few people get to win.
We have also seen time and time again that it is a game that is able to manipulate and change whatever ideology or behaviour you have to work towards its own benefit.
So the only way to actually "win" is to not play the game.
Right now that seems impossible because it is a massive collective action problem, however this whole platform is a testament to show that it's possible to overcome that kind of problem.
Reddit is a dominant platform that is starting to destroy itself. People are in turn finding alternatives such as Lemmy to satisfy the need that Reddit once did.
I view capitalism in the same way. It will never truly completely cease to exist (the same way Digg never truly died), but it can become irrelevant over time if we collectively decide to just use another system to satisfy the same needs that capitalism is satisfying today.
The one example that I can think of that tries to tackle this problem is the idea of free stores that are based on a gift economy. If more people decided to use this system instead of capitalism then capitalism will have less sway over people's lives.
And in the end it doesn't have to be specifically a free store that needs to be adopted by wider society but whatever it is does need to satisfy the same basic need that capitalism does in our current society.
Wealth without any kind of external indicators is 1) not generally a problem, and 2) are not generally the actual wealthy who are causing harm.
Are there millionaires who live in a 500k house and drive a Mini? Sure. But they're going to be on the low end of millionaires, not generally in the Capitalist class, just in the higher end of trades.
No one is out to deny people a comfortable house, modest vacations, and hobbies.
People are trying to solve for the kind of wealth that buys political power, or that can upend communities, or that has legislative sway.
Bezos cannot be anonymous, and still have the influence he does. Or Musk. Or even just the executives of publicly-traded companies. Anonymity is something that wealthy people have a hard time with.
The reason that most mid-level millionaires can be anonymous now, is because no one is intent on finding them all. It's not hard to if you're out to do it.
