Try to see money as a ablative material that allows to set up "alternative" realities. It has to be worn down and away by conflict, refugee streams, economic, environmental and social collapse before actual change can happen.
I live in Trump country. My faith in humanity is at its nadir. I won't give up, not ever. But I think its clear what will make a difference (e.g. banning SUVs, coal, and fracking, restarting nuclear, subsidizing solar, population control, etc), and what won't (banning plastic straws, putting recycle bins everywhere), and I think its wise to accept that humanity, in the best case, will undergo a (voluntary, controlled) Contraction. In the worst case, it will be involuntary, and catastrophic. That's it. Those are our only two options.
What do you think is the root of the problem? You say faith in humanity but do you mean these people are failing? If so, are they the cause of it or possibly the media they/we are consuming? If you agree with that and that vested interests influence that media then what can we do? It seems like a fatal cacth-22 for the kind of democracies we have.
I live in Trump country, too. Which means I know a handful of people (not even anywhere near a majority) love to throw their impotent tantrums and we need to stop letting that scare us.
