Joseph E. Stiglitz, writing in The Price of Inequality: How Today’s Divided Society Endangers Our Future (2012):
The top 1 percent have the best houses, the best educations, the best doctors, and the best lifestyles, but there is one thing that money doesn’t seem to have bought: an understanding that their fate is bound up with how the other 99 percent live. Throughout history, this has been something that the top 1 percent eventually do learn. Often, however, they learn it too late.
