You are correct that all models are imperfect, and you can compute second order corrections to my sketch of rents (e.g. subtract overhead for offshore operation).

None of this changes the conclusion that Deepika (a real person and a friend of mine, albeit not named deepika) has escaped poverty thanks to her job at a call center. Based on our previous conversations I know you dont consider her as valuable as a hypothetical american (ugh, dirty foreigners with animal gods and spicy foods), but that's simply a normative difference.
