OK, I've been extremely busy for a couple of days, but here's my observation w.r.t. joint families. It would indeed be lovely if grandparents were to stay with a couple and help bring up the kids. It is good for @Mad Indian that his parents have agreed to this proposal. However, if there are multiple children, whom do the grandparents stay with? Let us say there are a couple of brothers. Both would of course want the grandparents to stay with them. How is this conflict going to be resolved? One possible way of course, is to have everyone stay in the same house. 2 grandparents + 4 parents + 4 kids = 10 people, maybe 12. In an urban area like Bangalore or Mumbai, getting a house large enough and comfortable enough to house 10 people (5 bedrooms?) is beyond the reach of most people, save the top 0.05%. A family of 4 (2 parents + 2 kids) can make do with a 60 lakh 2 BHK apartment, but a house for 10-12 people is pretty much impossible. To maintain the same standard of living as a couple + kids in 2 BHK would have in a similar location (close to workplace and shopping areas and hospitals etc.) will require around Rs. 8 crore based on prevailing real estate values. Let's look at the issue of property ownership next. In almost EVERY case I have seen around me (across castes, communities, regions, etc.), siblings end up becoming sworn enemies and fight bitterly over property post their parents' death, sometimes even before. A HUGE percentage of property cases in our Indian courts are among relatives, siblings, etc. This is such a contentious issue, and everyone wants some property to call their own. In the above-mentioned scenario of a large joint family of 10-12 living in one house, purchased with shared money, how is the property distribution going to be equitably managed? They will end up fighting like cats in most cases. Coming to the issue of ego and the issues of staying under one roof by today's generation. Actually, it is not just the "new generation" which has an issue, whom we always blame. Today's grandparents and senior generation is not the same as before. It is not just the daughter-in-law who has an issue with her mother-in-law. In an equal number of cases, it is also the mother-in-law who has an issue with staying with her daughter-in-law. The older generation of today values its independence very highly. They just don't want to work as "free maids" for their daughters-in-law (in the own words of several senior citizens). I am not sure if the classical joint family will work in today's nuclear urban society due to the above constraints. These constraints and issues did not exist in the agrarian rural economy, but that is fast changing, and will continue changing due to economic imperatives. Whether preservation of the joint family is desirable or not, I do not know. But whether it is possible or not is a different question, to which I think the answer is no.
