A few days ago, I was talking to a close acquaintance who used to live in Bawla, a small town about 35 km west of Ahmedabad. It's an industrial hub with rice processing mills, cotton ginning units, and pharmaceutical companies. The acquaintance, from a very ordinary middle-class background, lived there because his son worked in one of the major pharmaceutical units nearby. However, he recently moved to a housing society in Ahmedabad, and I asked him why.
