Failing to Reject the Reagan Revolution, and mass embrace of the Jack Welsh style "trickle down" economics lie, by BOTH parties was the point of no return, almost half a century ago at this point. This car was already totaled.
Citizens United years later was just a victory lap by the owners pissing on the long dead corpse of the dream of societal equity.
Trump is just another symptom of that intransigent reality we all live in.
I'd say hope for collapse, as painful as it is, to have any hope for a better life for our children, maybe, but oligarch greed made climate change and at this point inevitable ecological collapse in the coming decades means there really isn't hope for a better society/civilization for generations(if they eventually develop technologies to better cope with the new hellish climate reality) if at all.
In the near term, people increasingly not being able to afford basic necessities like housing and food will lead to increased societal violence, but that likely won't cause collapse.
Climate scientists are increasingly warning of ecological collapse, meaning core climate systems will fail, like the Atlantic Gulfstream which will cause global famine and destruction, and that might be the end of human civilization all together, we won't know until we do it within the next half century, and see the full extent of our fine work, a climate hostile to agriculture, dependable fresh water, possibly even standing structures not made of steel and concrete.
But man are we speeding towards that cliff for short-term private shareholder profit, wheeeee!
