I think everyone gets why he chose an LLC<p>- can make political contributions, People complain about it alot, but as Bill Gates said,even his own fortune is a pittance compared to what the government spends each year.  Political persuasions moves the needle in the US more than charity ever could hope to. Why give up on that option?<p>- invest in companies, how many people here have said they&#x27;d invest in SpaceX because they think its good for the human race.<p>- charities have to give a way a certain percentage every year<p>- charities are subject to alot of rules and oversight.  You don&#x27;t get rich by having other&#x27;s tell you what to do with your own money.<p>Would you feel a bit pissed if you put the vast majority of your wealth into a charity and then found out that, that meant that you really couldn&#x27;t do the things that were important to you due to the tax rules imposed upon charities?<p>What he&#x27;s doing is smart if he wants to have the maximum impact on the world.<p>Consider the alternative.  He&#x27;s doesn&#x27;t ever need to sell any FB shares in his lifetime, he&#x27;ll just get loans from the bank against his shares, so this isn&#x27;t really about dodging taxes.
