Many people now have this mindset of "it's not my job" when it comes to others. Maybe driven by internet discourse popularising it? Maybe because atomised people make better consumers and won't organise together to uplift each other?
For example, someone drops litter. Maybe a pepsi can. People walk past, look at it, the wind even blows it to their feet, but they don't pick it up. They know the litter is a problem. They know they want cleaner streets. But they don't pick it up. They have power, but don't see themselves as having responsibility. Not just occasionally, but nearly 100% of the time (for this particular issue).
Then I was talking to someone in my extended family, who are several years younger than me. I brought up that they don't give attention to one of our younger relatives at family gatherings, who is a young only child. Instead her and her sibling both sit on their smartphones, doing whatever. No sense of "this kid doesn't have playmates at home" or how kids (and humans throughout their life) develop through input from others, even just innocuous input. Her response? "We don't really see it as our job". Excuse me? I know for a fact people played with her and ger sibling when they were younger (since I remember as a preteen and teen playing with them, and making sure to play with the older one attention when the younger one was getting all the attention).
Was it like this before or is it new? This mentality of owing nobody anything.
When I see kids I try to give them attention, even just looking at them, rather than ignoring their existence, because I think it's important for them. It's a social responsibility too. That's how they learn verbal and non-verbal communication, emotional connection, comfort around others and whatever else. Maybe that even becomes a positive experience they remember, like most of us remember some random interactions with strangers. Which reminds me: I moved to the UK from the US as a toddler, and supposedly said to my parents after moving here "nobody here talks to you".
We're all made by our roles: parent, sibling, niece, uncle, friend, mentor, mentee, neighbour, coach, occupation, consumer, producer etc. However I know cultures vary in how much they view themselves in terms of their relationships and responsibilities to others, as opposed to as an individual. Some people want friends to have people care about them or to have fun, some want friends also because they want the power and responsibility to be there for others, that comes with the role.
