Honestly, I hope one of the side-effects of the current crises is that there is a re-assessment of the value of multi-generational households. We are currently in the process of building a new home (planned before Covid-19) that will accommodate my wife's senior mother as well as provide a future shared home for our son.
They really sold us on a bunch of crap last century with the "atomic" family and suburban keep up with the Jonses bull.
