Well, but what does "caring" mean? It means that their well-being affects your emotions.
That would be an extremely reductive definition that doesn't really tell us much about how caring for others is actually experienced and how it manifests in the world. How would this for example explain sacrificing yourself to save another person, if the very core of caring is to create positive emotions in yourself? Dying is a pretty negative thing to experience and there will be no more positive emotions for you after that. I guess this idea that caring is in its essence transactional feels profound to people because we're so ingrained with capitalist ideology... but it's a lot more complex and multifaceted than that.
Lots of greenwashing going on here too. The nordic countries are just as capitalist as anywhere else, we just had a strong labour movement in the 19th and 20th century. And sadly, a lot of what was won has been slowly whittling away in the last decades due to the complacency and inaction of the generations after.
