These days I am working on relearning the math I've forgotten, and going beyond where I stopped in college. I have found that a combination of books, YouTube videos of lectures, Kahn Academy, Math Overflow / math.se, and subreddits like /r/learnmath, etc. have been sufficient.

I look at indigenous cultures who were able to resolve conflicts and share resources without hierarchical governments. They developed approaches to doing things western culture is only now relearning.

Also, your "best people" developed systems to addict us with little concern for their systemic impacts. If that's your version of best, I want better.
