Also I can understand taking that risk for yourself. Certainly it's way outside my comfort zone, but I'm not going to tell someone else they can't do something dangerous. But how can you go out and hire people to help you knowing there's a 25% chance they'll be giving their lives for you?
I think the problem is that most of us define "rich" by the accumulation of wealth, but for tax purposes it's usually defined as annualized earned income. Many billionaires pull no salary, and manage to defer capital gains so effectively pay very little tax.
