No one here, back in the US, ask a random person on their first visit, "How's family?", and see people responds with honestly and have a conversation about how our respective wives are giving us hard times! :)
Back in 2006, I traveled to US only once for three months and I realized, we have a much better family and social life in India, and decided to never move to US, even if I was pushed to go there. We enjoy a much better community life here, even though, we do not have all the luxury.
Generalizations are hard to make as we are talking about two countries that are both big and diverse. That said I do see why you say that and there is certainly that element to it in various places and communities in the US. However, lot of urban India is becoming very similar.
