Mainstream culture until Working Culture destroyed the infrastructure they needed to continue. The Utopians were started by a mix of individuals from diverse backgrounds with a common goal: Use technology to eliminate greed and need. The economics of ubiquitous dynamic manufacturing technology, combined with distributed power plants, had driven the cost of production down to near zero, especially when raw materials were recycled from landfills. To the Utopians, it was a logical step to use this infrastructure to efficiently fill the needs of large numbers of people. Despite core disagreements with Working Culture on the effects that Utopian society was having, or would eventually have, the two co-existed for quite some time. Working Culture managed to put limitations on the progress being made, possibly because not even the most ardent Utopians could really claim that they knew where their philosophy would ultimately take humanity.
Social status became the new wealth, and ironically, many Utopians were greedy for this new form of wealth and allowed it to blind them to opposing viewpoints. With clouded judgment, some Utopians would willingly break the progress laws just to get name recognition. At the time, the boost in social status was, for most, more than compensation for the jail experience that violators received.
The exact cause of the war between Utopians and Working Culture is not known, but historians point out that there may not have been a single cause. Working Culture and Utopians never agreed, and it may have been a relatively minor incident that sparked the fire of war. The Utopian philosophy is ineffective without the infrastructure to implement it, so the defeat of the Utopians was largely due to the destruction of some core manufacturing technology.
