500 Million is not effortless for anyone on planet earth. Mark Zuckerberg has somewhere in the range of 7 to 10 billion dollars. 500M is somewhere between 5 and 7 percent of his net worth. I realize that money has less marginal utility to billionaires, but donating 5 to 7 percent of what you've earned in your whole life is nothing to sneeze at. I'm pretty sure Mark thought about this decision as he has never been known to throw money around, and for you to dismiss it as "effortless" is fairly absurd.
