I was born to a 20min neighbourhood. My market town had a library, hospital, surgery, police & fire station, schools, banks. Green groceries, butchers - abattoir, sweet shop, cafes, pubs, cinema, theatre, toy shop, iron mongers, milk man, deposit return, all locally owned businesses. Then out of town retail came. End
This applies across the world too, especially the global North
