I have no doubt that we can create a really miraculous future. I am just increasingly pessimistic about our collective desire to do so.
So what if there’s a low collective will at the moment. Do your part to be part to grow the collective will to good. Go volunteer for a good cause (food bank, community organizations, etc.), donate to good causes, just be friendly to other people you see.
The problem is, that way of thinking is just like the "co2 footprint" - individualise responsibility from where it belongs (=the government) to individual people, and let's be real, outside of the very last action item many people don't have the time and/or the money.
At some point, we (as in: virtually all Western nations) have to acknowledge that our governments are utter dogshit and demand better. Optimism requires trust in that what you work for doesn't get senselessly destroyed the next election cycle.
