Thank you Kanaaz for your rich and detailed reply! I do think that in this era of globalization, when family members can be spread far and wide not only between states or countries but even by continents, it is hard to maintain caregiving customs and patterns which evolved over centuries. In the Indian context, what happens if the "privileged" eldest son is an engineer in Silicon Valley and the parents are in Mumbai? Does the responsibility then transfer to those who are living closer to the parents? Also, one would imagine that caregiving responsibilities would be to some extent apportioned to the amount of time individuals have available– i.e. if an adult child is single, presumably he/she would have more time to devote to the aging parents than siblings with families of their own. Finally, if it is assumed that a woman moves in with her in-laws after marriage, what degree of power and responsibility does she have in making decisions about taking care of her in-laws? Is she accorded the same status as the in-laws' own offspring?
