Not sure I follow your objection. Of course it's proportional, but that's irrelevant. It's the moving target that accentuates the disparity in income. Zuckerberg, Jobs, Winfrey, etc weren't in the 1% when they started, but each of them displaced someone making less than 500K, and in doing so show that the wealth of the richest increased by a huge number, which may not be even true.
