Indeed, and much of this comes down to hereditary wealth - one of the world's great evils.

What we should do as a society is, whenever a person gains above a certain threshold of wealth and refuses to give it up to the state, they are forcibly sterilized and banned from adopting, thus ensuring no heirs.

And anyone who already has offspring has their wealth taxed at 100% above that threshold.

This might sound dystopian, but just imagine if this policy had prevented George W Bush from ever being born. That in itself would be a public good.
