This isn't about Jobs giving money, this is "let's hate on the rich people until they have less money". Gates, Jobs, and Buffett are all tremendously wealthy. Gates and Buffett are heroes for what they do, and they are realists. They couldn't possibly spend all that money, unlike the moronic sultans who seem to try, with gold plated mansions. Gates and Buffett will be remembered as probably the most philanthropic people who ever lived (in terms of dollars given). And rightly so, they should be remembered for their generosity.
Jobs, however, might not be as generous. If he donates large sums of money, he does it privately. But should someone as rich as Jobs be expected to donate? We, as less-than-multibillionaires, can say what we would do in Jobs' position, and criticize him for doing other things, but it's his money, and he may do what he wishes with it. He's not stingy for not donating, he just has other ideas. Not our place to tell him what to do with his money. If he wanted it all burned upon his death, again...not our place to say what to do with it.
Or, we could talk about how the sultans and kings of the middle east are pissing away billions on exotic sports cars, palaces, and other things of little moral value.
Nah, let's talk trash about the respectable businessman who will likely die before the end of the year.
