@JohnBrady An interesting bit I see in that article is equating collective action with systemic action. Though I appreciate and strongly endorse the importance of individual action, I think the author/article is a bit simplistic in how it approaches the discussion of what individual action is and/or how it equates to collective action. When I act as an individual I do so knowing that I'm not alone in that action. I am never just an individual. I am, at birth, born into the family of humanity. From the moment of birth our survival and wellbeing is tied to those around us. In much of the world this collective identity is still central to daily life. It would seem that in the wealthier nations of the "Global North" we have forgotten it.
Years ago, in the 1990s I volunteered and then worked at our local adult literacy agency in Memphis and really came to appreciate the "slogan" of one of the national literacy organizations: "Each one teach one". A simple notion really. If we all take action our individual action adds up. And it showed in our local agency as people, both students that needed to learn to read as well as volunteers, came in as individuals. But what a beautiful place it was to be. At any given moment the place was full of people learning and teaching, all individuals that added up to a collective. Here one could see with their own eyes that individual action adds up to collective action.
Describing any action as individual action makes the mistake of forgetting that we are never individuals. Which perhaps speaks to a larger problem of the culture of capitalism and beyond the scope of this reply!
