At this stage a story from real life is best -
There was a soldier in Indian Army called Anna Hazare. He was a truck driver and narrowly escaped death after a shell exploded near him during Indo Pak war of 1965. He took retirement from army in mid 1970s and returned to his native village, Ralegan Siddhi described as "one of the many villages of India plagued by acute poverty, deprivation, a fragile ecosystem, neglect and hopelessness"
Anna Hazare set about to change the village (he remained a bachelor through his life). With the help of villagers he banished alcohol, dug lakes to hold water (for droughts) and built a school. Today after 40 years, there is no unemployment in Ralegan Siddhi, no poverty, no crime (because there is no need for crime). Yes he is dictatorial in some ways. There are rumors that love affairs are frowned on, but in no way is it a patriarchal society. Quite the opposite with all women knowing how to read and write. Perhaps I feel the villagers themselves have become wary of love affairs since they know it causes envy, lust, jealousy and after quarter of a century in lap of peace get annoyed if someone tries to break the pattern.
Also alcohol and tobacco are banned in the village. In exchange people get cradle to grave security, loan, free education till high school, good health care. The World Bank Group has concluded that the village of Ralegan Siddhi was transformed from a highly degraded village ecosystem in a semi-arid region of extreme poverty to one of the richest in the country.
It is not impossible to imagine Theravada based Kibbutzes (above is but an Indian version of Kibbutz, though in a Kibbutz private land ownership is not allowed) of the above type. It can ideally happen if a Theravadin billionaire can purchase a large island for Theravadins (for say 10,000 people). These 10,000 have to accept eight precepts before entering. They will be farmers and cooks as well as monks. Tasks will rotate. Those above 50 and 60 will be allowed freedom to meditate 24 hours a day. Those below 25 will be allowed to have sex to procreate but under very tight restrictions.
If anyone has such a place in mind please let me know. I am willing to eat one meal every 4 days, if I can somehow escape this world which has gone to hell in a handbasket. I will clean toilets, plough the field and look after the cows. I am also a good cook.
