Selfishness

Maybe it's just me being more aware of it but have people become more selfish lately? I'm not talking about some profound way to live life. I'm talking about the most mundane things in everyday life. People going through life as if they're the only one that matter, as if their time is the only valuable one. It's something that's depressing to watch and experience. It takes so little and requires very minimal effort to make other people's lives better and yet so few actually do it.
