Photographers Capture the Gap Between the Rich and the Poor

When people think of inequality, they often think first of the lives of the world's poorest people. This Friday, a new book puts the spotlight on the richest. 

Little also views the collection as a response to the 1950s photo exhibit Family of Man, which optimistically tried to show that we are all humans, part of the same world. 

"I have huge respect for [that exhibit]," Little says. "But I felt like, with inequality skyrocketing all around the world … it's hard to claim that we're all in this together."
