How is it motivating? If anything, it highlights the growing disparity of wealth in the world. Seems like humanity is going backwards.
Does that sound too cynical to you? It's just my opinion, but I'm not going to hold it against mankind that some people have A Lot More Stuff. Wealth is not a finite resource, it can be had in a variety of different ways for the creative. Inheritances aside, if getting rich is the side effect to booming innovation, I'm not too bummed about it. It's business, and the rich have no compuctions about selling you something to feel better about mankind's slow devolution into hedonism, so why not get on board with them?
When you become rich, you will have more power, influence and resources to Save The World. Start there?
