Dude just structured his wealth so that he can exercise political power, including giving money to politicians, long after he is dead.
I'm not unhappy about that, but come on, let's be clear about what it is. If the money was going to a different set of politicians, ProPublica would publish an article about how corrupt it was.
Nor am I unhappy about him being rich. I just don't buy the whole "I'm not rich, my houses in Ventura and Jackson Hole are fairly modest!" shtick.
