That's what money is for. So you can buy things you want. To do that you also have to give away your money to the person who used to own those things, so they win too. The reason he got so much money is because he gave a lot of other people things that they wanted and they gave him their money. There's nothing wrong with that - unless you think trade is wrong and we should all be self-sufficient hunter gatherers, or that people who work hard to serve others should not be rewarded for it.
