I mean, sure the old school giants like Exxon, Walmart, Microsoft, et al. give incredible sums of money to charities. Hell, even Goldman Sachs gave over $300 million in 2010. But just imagine how much money the Apple corporation must be contributing...
Apple has done far more to make the world a better place than any corporation I've ever heard of. Far more than any government in history ever has. Far more than any charity every has or ever could.
Capitalism benefits people. Every dollar in profit Apple puts in the bank is represented by thousands of dollars of improvement they've done to people's lives.
Capitalism is the cure to poverty-- when socialism is tried the countries quickly become hellholes. When capitalism is allowed-- as it was in the US in the past-- the country went from 3rd world to 1st world in a couple generations. India doubled the standard of living of over a billion people in 20 years simply by reducing red tape, allowing a little more capitalism. China has done even better on that score.
Apple could burn all its money in a big old bonfire, and it still would have had a more positive impact on the world than Bill Gates charities ever will. (In fact, I suspect Bill Gates charity work is actually making people's lives worse due to misallocation and undermining economies in those regions, combined with bad economics, but I haven't studied it closely enough to be sure.)
