What's the point of billionaires? O

[Middle-aged Europe]

Or, to be less opaque, does the economy in general benefit from the presence of billionaires and multimillionaires? Do they invest more (or in better ways) than if the equivalent capital was invested by public bodies?

Or is there no benefit, but they are a necessary noxious by-product from the economy that we have to just deal with?

There can't be light without darkness.
