On the contrary. Most of that money is the capital that makes up Amazon and its subsidiaries, which has consistently grown faster (created more wealth/benefit) than almost any other entity in our society.
That's your neoliberal take. Personally, I'm a little dubious that wealth created is 1:1 with social benefit created. But to say that his bank account benefits nobody would be a misrepresentation.
For society, by making the distribution of goods/services more efficient. Amazon enriches our lives (compared to no Amazon) every time anyone uses it. The resources we all save, the delta, go partially to Mr. Bezos and owners of Amazon stock in the form of profit. They are rewarded for having allocated their capital efficiently. They can spend the money on whatever they want, but it is mostly allocated back into making Amazon more efficient -- not locked away as the gp suggests.
Bear in mind this is the extremely idealistic neoliberal take.
