Yet another curve that inflects in the mid-70s: Top 0.1% share of wealth
(Via the Guardian.)
What I would really like to see is a chart that tracks the bottom 90%, the top 10%, and the top 0.1.%. (It takes a minute to see, but the top 10% is left out -- the comprador class, you might say -- and that's why the curves aren't inverse. There's still momentum for the bottom 90% until the mid-80s.)
Incidentally, we can't blame this on Reagan; this change took place in the Carter administration, and could well have been prepared for before that.
