$60 billion is incomprehensible to most people. It's money so big that it is not money anymore, it's the power to make society-level decisions. In a sense it is so big that it becomes an obligation--see Bill Gates and Warren Buffett.
Steve Jobs himself was not nearly that rich because he made decisions for reasons other than money--like selling all his Apple shares out of spite when he got fired. And sinking huge amounts of his personal wealth into NeXT to design the computer he thought should exist (but which never sold well).
In a macro sense it is good that it is so hard to make large sums of money. It ensures that the people who make that money will at least have some ideas about what to do with it. Contrast with the typical fate of lottery winners. Most self-destruct in pretty short order.
