Again, all that doesn't change your life much. The difference in quality of like is nowhere close to the gap you bridge when you can stop trying to make a living and doing daily chores. You hit diminishing returns.
But being able to influence politics, the economy, and knowing personnally many people that can, is a huge difference in what life you can experience.
I do agree it hits diminishing returns, but I do also still think the difference is quite stark. Each level up it affects which things you have the freedom to just do vs. which things you need to plan. You still hit those barriers where you have to plan and budget as a millionaire for things that are relatively within what regular people might dream of.
At some point additional wealth stops buying you significant comfort, but starts buying you significant power.
And to be honest, I think the area where that happens is a problem. I'm fine with people enjoying a life of comfort, I'm not so fine with people buying significant over others, over the society in which we live, simply because they have more money. It's a danger to democracy.
Any kind of concentrated power is a danger to democracy, but you can't setup any system that can counter that, because it will just concentrate somewhere else.
The only way to avoid this problem is for the people to actively, on their day to day live, think and act toward the society they want to co-create. Power to the people implies responsability for the people.
And we are nowhere near that. People don't want the responsability. They have enough on their plate already with their personnal life issues. They don't want to have to choose every day what to buy, what to read, what to watch. They don't want to include the entire what they think society should be in the process of choosing education, home or a job.
So they vote to delegate the power and responsability once in a while and call the resulting oligarchy a democracy. Semantics is way easier than implementing the real solution.
But being able to influence politics, the economy, and knowing personnally many people that can, is a huge difference in what life you can experience.
