I think this might be the best time to start having these conversations: when things are getting bad for almost everyone, and there is so much governmental upheaval that changing the economic system becomes a lot less disruptive than it would be during good times. It's only going to become more and more clear that capitalism is failing.
My favorite economic system so far is a land value tax with UBI. I still don't know exactly how businesses would operate, but this system would eliminate the parasitic generational wealth siphoned from hoarding property and housing. It would also allow for people to not work if they're unable to.
I'm sure it's probably just delusional hopium that we could ever get through the threat of fascism and come out of it with a better system than what we had, but that's about all I got left right now. The rest is just doom.
Find a Mormon. They will be ecstatic to do this for free. Of course all the social events will be church related and they will certainly try their best to convert you... But harassing people into participating is what they're best at.
