Most of the current elderly also grew up in an era where they believed cities and urban areas were bad, so they moved out to the suburbs where everything is farther away and requires driving. It requires a lot more effort to do anything and they have effectively isolated themselves.

My grandparents who lived in a city could walk down the street, get groceries, and easily meet friends for a snack or chat. Even when they were alone, they were part of a community. My parents' generation all live far away from each other, struggle to get out of the house, and are scared of strangers.
