One way to look at this is that Zuckerberg just robbed the treasury of $45B.  Part of that would have come in through capital gains taxes and the rest through the estate tax.<p>What they do with that money is up to them, not the state.  It&#x27;s a pretty sweeping end run around the taxation system.<p>Maybe we&#x27;ll get lucky and he&#x27;ll use the money to good end like Gates is doing.  And maybe not.<p>This is a heck of a tax code we&#x27;ve got, it&#x27;s trickle down on a grand scale.
