I am reading Octavia Butler's Parable of the Sower. If you want to understand what is in store for us - please read that. It is our future all of us who are not rich and can afford to build fortresses.
Even the future for the rich eventually breaks down as in The Children's Bible. The questions apparently from the super rich to Douglas Rushkoff now are how they can keep their security guards loyal as they bunker themselves and their families away. The answer is you can't. https://onezero.medium.com/survival-of-the-richest-9ef6cddd0cc1
Try American Wars for what is coming as the US breaks apart - it's excellent. And follow the UFO/UAP story as it unfolds - why do you think they're here? Are they scavengers or are they genuinely interested in warning us about our future?
Yes I'm a science fiction writer and I have my own theories as to what our future might hold.
