Katherine Boo said this quote

In the age of global market capitalism, hopes and grievances were narrowly conceived, which blunted a sense of common predicament. Poor people didn’t unite; they competed ferociously amongst themselves for gains as slender as they were provisional. And this undercity strife created only the faintest ripple in the fabric of the society at large.The gates of the rich occasionally rattled, remained class. The poor took down one another, and the world’s great, unequal cities soldiered on in relative peace.
