The argument is even more compelling if you keep going: Should we allow septillionaires? Someone with $1e24 could give $1 trillion to every person on the planet

The argument is even more compelling if you keep going: Should we allow septillionaires? Someone with $1e24 could give $1 trillion to every person on the planet every year for 100 years and still have 99.99% of his money left. How much power and influence over the world would these people have, while the rest have comparatively close to zero? I think we all agree that wouldn't work for a functioning society.
