Bright Future And New Enlightenment

Whereas The Complete Psychotechnic Leauge, Volume 1, contains only four stories, Volume 2 contains nine, including one about slower than light interstellar travel and two about FTL. After a slow start, this future history series leaves its launch pad. Sandra Miesel's "Forward" ends with a utopian vision:

the Psychotechnic Institute is powerful and prestigious;

its bright human future seems inevitable;

hugh tech triumphs;

the Second Industrial Revolution benefits everyone;

there is neither hunger nor homelessness;

work is a privilege, not an obligation;

everyone speaks semantically rigorous Basic;

the Solar Union space navy guards the System;

there is a New Enlightenment.

So why is there global conflict and interplanetary war in the third story in this collection?

When Hollister experiences armed conflict on Venus, he has:

"...an almost holy sense of his mission to prevent this from striking Earth again."
-"The Big Rain," VIII, p. 216.

He has trained as an Un-man and we already know of the UN anti-war policy. So why does war strike Earth again?
