Exactly.
But as one who actually lived on a dollar a day (seriously) for about a year, it is not actually the "billionaire" that is the problem, he/she is a symptom.
The problem is the State, its monopoly on violence, the dispatch of Corporations that are effectively the Tax Collectors and favoritism of the State towards large corporations (such a Limited Liability of owners, Patents, trademarks & copyrights, licensing and regulation).
No state, no billionaires.
@bonifartius imagine being so fucking envious and materialistic that you've convinced yourself that having more stuff than you is somehow an evil act just on its face, but that somehow you having more than most of the rest of the world isn't.
