The 1960s and early 1970s were a time of rebellion. These rebels had no clue to what life meant. There was some truth in that we need a new lifestyle and must reconnect with nature, but Satan took over these pathetic attempts at rural self-sufficiency experiments in free love and socialism.
One of the most famous communes that still exists is Twin Oaks in Virginia. Kat Kincade got excited about B.F. Skinner's book, Walden Two, and started their commune 25 years ago. Even she left for a period of nine years. After 25 years she has a follow up book titled, Is It Utopia Yet? The answer is not only "no" but it is a ridiculous social experiment.
In the 1960s there was a revival of communal living by young people--mostly hippies--who were mainly united by a common dislike and distrust of industrial societies. Their communes, which aimed at a high degree of self-sufficiency, seldom survived for long periods of time.
Another Hippie commune that has lasted for 25 years is The Farm in Tennessee. Steven Gaskin founded it and is still living there. At their website thefarm.org, he explains that after 13 years they had to introduce some capitalism to their pure socialism that wasn't working.
