Both of these quotations are from today's New York Times Opinion pages.
"Not since the Roaring Twenties have the rich been so much richer than everyone else. In 2005, the latest year for which figures are available, the top 1 percent of Americans — whose average income was $1.1 million a year — received 21.8 percent of the nation’s income, their largest share since 1929. Over all, the top 10 percent of Americans — those making more than about $100,000 a year — collected 48.5 percent, also a share last seen before the Great Depression."
...and, from a different column...
"Researchers led by the psychologist Dacher Keltner took groups of three ordinary volunteers and randomly put one of them in charge. Each trio had a half-hour to work through a boring social survey. Then a researcher came in and left a plateful of precisely five cookies. Care to guess which volunteer typically grabbed an extra cookie? The volunteer who had randomly been assigned the power role was also more likely to eat it with his mouth open, spew crumbs on partners and get cookie detritus on his face and on the table."
