But if writing about people who are not yourself is illegitimate, then the only legitimate work is autobiography; and as a reader and a citizen, I don’t want to live in that world.

My job is to lay it out clearly, not to give my policy prescriptions.Very little journalism is world changing. But if change is to happen, it will be because people with power have a better sense of what’s happening to people who have none.

There's some way in which we would prefer not to see very clearly the immense gifts and intelligence of some of the people who live in our most abject conditions. Maybe there are some things at work in deciding who gets to be society's winners and who gets to be society's losers that don't have to do with merit.

When I pick a story, I'm very much aware of the larger issues that it's illuminating. But one of the things that I, as a writer, feel strongly about is that nobody is representative. That's just narrative nonsense. People may be part of a larger story or structure or institution, but they're still people. Making them representative loses sight of that. Which is why a lot of writing about low-income people makes them into saints, perfect in their suffering.

I was spending a lot of time in Mumbai after I met my husband, who is Indian, and while parts of the city were prospering like crazy, I couldn't quite make out how the new wealth had changed the prospects of the majority of city residents who lived in slums. So after a few years I stopped wondering and started reporting.

I've said it before and I'll say it again: Never trust anyone who tells you how people come to trust them.

People naturally long for a bit of the wealth that is whorling all around them, and if the work and education available to them won't get them closer to the comforts that they see others enjoying, the temptation to take shortcuts can be fierce.
