You sit down and listen to the record player with your kids.
I don't know man, I am sure if we scoured the ideas people who study this subject have put out, there is plenty of great things we could do. But anything that is not the Wealthy, White, Heterosexual, Male agenda is dubbed 'socialism' and trolled by paid propagandists. The best we can do is vote in candidates who decide to run for the job and have a chance to actually get anything done without selling out too hard. It is really not that hard of a job, mostly Americans takes care or ourselves best when left alone, but it makes it much harder on the people that can't take care of themselves.
My hippie idea is to have a mega city, have it fit a hundred million or so people, so that they can learn from one another, provide centralized food (no need for plastics/fuels for transportation), so many benefits. Anyone that cannot take care of themselves would be welcome, and have a home of their own and always have healthcare and food when needed. Every 500 years or so, open a new mega city and abandon the old one. Have a bunch scattered around the planet incase of a catastrophic event, hopefully some are habitable.
But yeah I would like Carter's mental facilities re opened with top notch monitoring of the facilities so no funny business goes on.
