In his lifetime he was one of the most famous (world-wide) Americans ever to have lived. He traveled around the world more than eighty times. There is a form of carbon named after him: Buckminsterfullerene.
Anyhow, he calculated that we would have the technology to save the world and fix everything by sometime in the 1970's. That happened, so now all our problems are basically psychological or spiritual.
It also so happens that a working psychology was invented/discovered in the mid 1970's and subsequently refined. It's called "Neurolinguistic Programming" (NLP) and it's basically the OS of the mind. Using NLP and off-the-shelf technology we can stop ourselves being foolish jerks and provide a high standard of living for everyone forever.
I suffered from crushing depression until my mid-20's and was totally cured, after considerable self-improvement, by a single intervention with Dr. Bandler (one of the co-founders of NLP) that lasted less than twenty minutes.
Let me repeat that in case I'm not being totally clear: A life-long depression that interfered with my ability to live a normal life (I was homeless for about four years after high school) was cured in a 20 minute session of NLP-informed hypnosis with Dr. Richard Bandler.
So, we have the psychological technology and the physical technology to solve all our problems.
It really is just a matter of getting the word out and putting our backs into it.
My specific recommendations to you are: 1. study NLP and go talk to practitioners, maybe even get some therapy; and 2. Study applied ecology (E.g. Permaculture) and start a small productive system (farm!) to begin to meet your personal needs in a economical and ecological manner.
"The plan was good, it was right, and no one had to get nailed to anything."
BTW, NLP is pretty easy to learn and it's a great career if you're at all good at it. An experienced therapist commands remuneration comparable to that of a computer programmer.
Last but not least, browse Rex Research: http://rexresearch.com/1index.htm There is a lot of weird crap in there but in between the crack-pottery you'll find mind-blowing cool technologies. The idea is to break out of your funk by confronting yourself with existing real-world solutions to all the various BS confronting us today.
My hobby is collecting powerful ideas, I can assure you the best things out there are really amazing and you haven't heard anything yet!
