Any books dealing with alienation?

I'm reading Time Out of Joint by Philip K Dick. Then on the side I read a few pages of Nightcrawlers by Robert McCammon. The thing these stories have in common is they portray people who are social and outgoing. Normies if you will. Time Out of Joint begins with two neigbor families hanging out together in the home, playing cards. Nightcrawlers begins with a policeman entering a mom-and-pop diner, the same one he eats at every day, and they start cooking his meal before he even ordered because they know what he always gets. Then the policeman starts talking to the waitress about his friend whom he's been trying to make her go on a date with for some time. When I read these stories it feels very foreign to me. Do people like this exist today or is this a thing of the past? Why do some of us live a much more alienated atomized life than this?
This is a TV series episode based on the short story Nightcrawlers.
