They seem to be suggesting it's better the money is earned through ownership. Which is funny as I'd lean the other way and say that beyond a point, allowing such large income through ownership and not actual work is a bad idea.

Note: Bezos and Musk, could ask for a hefty salary so they may work out to similar total income, unless someone else could run it cheaper and better. While hedge funds and inherited wealth that only own and don't contribute would receive less.
