Indians returning to India is old news. Not all Indians who come to America stay. Many return because they get home sick or they can't adjust. Many also return to India because they can get a better deal in India. For the same set of skills they can live better in India.
Bingo. Parent is right about the "better deal". Middle class in India is not the same as middle class in America. Maids and cooks are common for middle class in India. In metro NYC, you are looking at $60/hour for a decent maid team, costing you at least $180 for a decent cleaning of a 1 bedroom apartment.
