> When someone else gets richer and you stay the same (or increase at a slower rate), you're worse off. The increased average wealth/income increases demand and makes things more expensive for you.

One could easily argue that it makes things cheaper for you and everyone else, as rich people 'demand' things, e.g. a cellphone, economies of scale start to take over and make it more affordable for everyone.
