In reply to the discussion: Moving in with parents becomes more common for the middle-aged [View all]Warpy
(114,778 posts)is how quickly it was abandoned when Social Security was established. Instead of moving in with each other, when the parents retired they downsized their living space and preferred to stay independent until death. The truth is that living with extended family doesn't work for most of us, there is too much friction between generations.
In addition, it's just too easy to backslide into dependency when going back to live with the parents, just as easy as the parents treating them like dependent children. Such things have to be consciously avoided and that's a skill that's beyond a lot of people.
Any improvement in the economy will send those middle aged children out into apartments like they were shot out of a cannon. Their parents will hold the door open for them and slam it once they're gone.
