I know plenty of "spiritual" people and they seem to live in the same houses, receive the same packages, drive the same cars as everyone else. I'm sure there are a few people out there in yurts living off the grid but what % is that of the population?
The main problem is that people have rejected science and facts and substituted their own. That includes plenty of spiritual people, I'd even suggest they make up more than their share. My relatives all think the problems of society are because we "reject Jesus." Well, I beg to differ, for one thing the world Jesus lived in wasn't exactly a happy one for most people (and even the well-off ones, well aren't they supposed to have a hard time getting into heaven?) They even reject the thought that science can change with the facts (you are being wishy washy or deceitful if it happens.) Just look how many people have embraced something as loony as q-Anon, which started on a damn internet forum for shit's sake.
Unless most people--enough to influence who gets elected--will accept what science is increasingly saying about climate change, nothing much will get done. Those people will then have to accept the extreme measures that this new breed of politicians install, and accept them over many years because any fix is a very long haul. Good luck. This is the same public where a huge swathe of people compare wearing a paper mask during a pandemic to a being a jew under the Nazis... Unless, of course, some miracle tech appears that not only works but can make rich politicians and corporations a lot of money-- I'd say start hoping for that because that's about the only hope. We are far, far past the point of everyone planting a tree and try your best to remember to bring your reusable bag to the grocery store (if that ever was going to help anyway).
