"I think in part the reason is that seeing an economy that is, in many ways, quite different from the one grows up in, helps crystallize issues: in one's own environment, one takes too much for granted, without asking why things are the way they are."

People try to reconcile you to a disappointment in love by asking why you should cherish a passion for an object that has proved itself worthless. Had you known this before, you would not have encouraged the passion; but that having been once formed, knowledge does not destroy it. If we have drank poison, finding it out does not prevent its being in our veins: so passion leaves its poison in the mind!
