The Inverted Bell Cuve

I was directed to his WSJ article by Daniel Pink, wherein the increasing decline of the middle class is causing the once bell shaped curve these workers occupied in a typical statistical sample, to become inverted. The graph below from the WSJ article seem to indicate this phenomenon quite well:




Much has been made about the threat of globalization, outsourcing, and the automation of many intellectual as well as manual labor tasks, and it seem from the above graph that this notion is truly causing a shift in class structure. This is not good news for people like recent college graduates, data entry clerks, call center support employees, etc., but will make the people who occupy the higher level positions even richer, and ironically, the people on the lower who service them richer as well. These are indeed some interesting times we live in.
