So you want to make it so if you ever save up wealth you can never transfer it to another human, ever, aside from giving it to the government which is run by humans to hand out to other humans outside of your control?
I don’t see any other possible solution that will not create a level playing field for others. I think it would have to go a lot further to fix the ‘problem’ you describe. No one could hold any position of authority since after all humans are corrupt and it will be abused to create scenarios where someone gets an unfair advantage.
When you keep going down this path as a thought experiment there’s basically no semblance of human society that would work. Separate children at birth from their parents and randomize who raises who - congratulations, randomized genetic diversity gets more or less opportunity at random. That doesn’t really work either though, since factors outside of your control determine your fate and opportunities. There’s no winning. It’s a zero sum problem.
