Relative wealth is zero-sum, and relative wealth disparity can and does negatively affect you.

Let's stay your wealth/income remains static, but most people around you see a great increase in their own wealth/income. You are certainly less better off now because all this extra wealth in your area will increase demand for goods and thus prices. See Bay Area housing market for an example.

Yeah, my original comment simplifies. I'm just trying to find common ground with "grow the size of the pie" thinkers.
