How America's public schools keep kids in poverty | Kandice Sumner

Tue, 01 Nov 2016 15:08:54 +0000

Why should a good education be exclusive to rich kids?

A letter to all who have lost in this era | Anand Giridharadas

Thu, 18 Aug 2016 15:02:25 +0000

Summer, 2016: amid populist revolts, clashing resentments and fear, writer Anand Giridharadas doesn't give a talk but reads a letter.

It chides an idealistic yet remote elite for its behind-closed-doors world-saving and airy, self-serving futurism — for at times worrying more about sending people to Mars than helping them on Earth. And it rejects the exclusionary dogmas to which we cling, calling us instead to "dare to commit to the dream of each other."(image)
