Yeah, those graphs about "the 1%" have the annoying habit of always ending in 2007. I've made the point before that part of the reason why the wealthiest got so much wealthier than everybody else is because their wealth is so volatile (in the sense that they have a very high "beta" wrt economic growth). In periods of economic growth they get much richer, in periods of economic contraction they take a bigger hit than everybody else (see the hit they took around 2001 in Winner's graph). The "issue" is of course that the US has had many more good years than bad years, and so people with high "betas" got overwhelmingly richer. A little mentioned fact is that "the 1%" lost much more from 2008-2011, even in relative terms, than the average american.
