I'm not saying it's good, I think it's very concerning and potentially very destabilizing. But it is the way things are right now. It's also possible to be on the wealth-producing side and not see your savings disappear into the ether while still providing things of value to people that appreciate it. "rent-seeking" is a real thing, and much of finance doesn't actually provide any real value to society, but this isn't a simple black and white dichotomy across the have's and have-nots.
We ought to find ways out of this mess, ideally something that doesn't involve communism and the typical humanitarian nightmares that usually come along with it.
Self-perpetuating generational wealth is not a zero-sum game if said wealth is put to good work.
Having wealth morally obligates its holder to put it to use to benefit others. I think we all intuitively understand this; it's the impulse behind calls to "tax the rich!"
People the last 500 years who put wealth to good use, even in modest proportions, are part of the reason western culture is so rich. We would not have Bach, Mozart, and Beethoven today if someone hadn't employed them (though I do decry the relative poverty some composers lived in and some OSS maintainers currently live in - come on, people). And modern infrastructure wouldn't exist if capitalists hadn't at one time thought it worthwhile to invest in railroads.
