When my family and I lived overseas (southeast Asia) we saw many more multigenerational households that we have seen in the United States.

I am not ready to predict how quickly the western world will choose or have to choose living in multigenerational homes, but I do agree that there are benefits. The hard part will be moving past generations of mindset shift. From a cultural standpoint, I was trained to leave so the idea of moving back in with "mom and dad" is hard. However, I see the possibility of needing to invite a parent or parent-in-law into my home.
