That's fair, but if you notice a great deal of the letter is simply telling the child about the great achievements and dreams of the parents - if there's one thing I've learned the hard way, it's that dreams are easy to put into words and fuckin' hell on wheels to make reality. Philanthropy is a good social construct, for sure. I guess maybe I just have some inherent bias against preaching from atop the mountain of wealth inequality, a position that was obtained through a combination of luck and timing as much as any pure personal willpower and genius.

Exactly. Bill Gates came late to the game. He pretty much had to conquer the whole world before developing an interest in philanthropy. Now it's his "real work" and I guarantee you he'll be remembered more for that than MS-DOS!

Zuckerberg, like Gates, is a brilliant but deeply flawed person. However, Zuckerberg appears to be maturing much faster than Gates. I have lots of hope for him left.

What about the concrete initiative of just paying taxes in each countries where the real business is done?

Well, if you consider the double irish with a dutch sandwich designed to take that money from states (who would use that money to finance stuff such as public services, medical insurance, social welfare,etc.), the market manipulation during the IPO, the spammer methods and a transnational corp whose business is the collection of personal and private data from users while trying to replace the web/internet among other wrongdoings, all to put that money in zucker's hands (and a few others) then it becomes obvious that this has nothing to do with philantropy or altruism, to the contrary it's narcissicism, ego and maybe guilt.

Hmmmm. Is locking down the entire internet worth $45B?
