But... money becomes more money precisely because it's invested into companies that sell products and services that people buy, and use most of that money to pay employees, office rent, factories etc.

Or in other words: money grows if you use it. If you just put it in a bank account it slowly erodes away under inflation.

that's the catch-22 type deal in the end which makes wealth-inequality the only outcome as the super-wealthy will always benefit more than everyone else when that money is spent and there is no incentive to limit growth

personally I think the only real solution is slowing down by reducing incentives to keep growing money (or stock value) by implementing some kind of tax ceiling in turn slowing down innovation and instead hoping that giving more people the ability to grow (easier access to education, healthcare, opportunity) eventually outweights the disadvantages of having such a ceiling
