Inequality

I came across this graph in my web-surfing today:

(from http://lanekenworthy.net/2010/07/20/the-best-inequality-graph-updated/)

Since 1979 the really wealthy have seen their income soar like never before.  Meanwhile, the rest of us have been stuck in the mud.  Another way to put this is to say that virtually all of the income growth since the Reagan years has accrued to the wealthy.
Doesn't that bother anyone else?
