Rod Serling as "Creator" is deceptive. He was probably in an executive capacity with little "creative" contribution. In other words, they used his august name.
If memory serves, this programme did not last a full season, and its 45 minute running time is a mystery. THE NEW PEOPLE was very much a product of its time, inspired much less by LORD OF THE FLIES than MOD SQUAD. It showed. To be honest, however, during the late '60s -- which I remember very well -- more than one middle-aged individual wondered how well all these griping young people could do if they were left to re-shape society. It is a small detail that starting from scratch in an environment red of tooth and claw is not the best way to test a high-falutin' hypothesis. The only "old guy" dies a long and expository death in the first episode, and life, such as it is, begins for the new society. Of course, by 1970 both great powers had high resolution spy satellites, although with non-Pacific targets, and it would be a matter of maybe two or three casualty filled years before things would be put to right. If they ever gave it a thought, that is probably how the "creators" planned to end the series.
For some bizarre reason, however, I found the theme attractive. Perhaps as a failed man in his middle-20s, I wanted to be off by myself on a non-desert isle with a nice high mountain at centre from which to watch the Sun go down and the Moon come up.
