A community based on a vision of a perfect society?

In 1516, Sir Thomas More wrote a book called Utopia. Later, in the 18th century, Robert Owens created this legendary society called New Harmony in Indiana and started this colony there. After about 2 years, the community crashed and burned because, well, there were all kinds of issues (manufacturing, labor, etc.)

P.S. You can trust this because I got this from a U.S. History textbook :)
