There is more to it than merely having survived ...
Kirk tells Edith Keeler that "one day," meaning, in his time, the people of Earth will no longer spend their resources on death, but rather spend it on life. Watch CITY on the EDGE of FOREVER and it's there, that brief dialogue. That's not to say that GR did not smoke his own publicity and took his "message" to the people about "his" vision for Humanity, but let's face it ... He was not a mere Television Producer, or Series Creator, he was The Great Bird of the Galaxy and TREK fandom encouraged him to project that. By the time TNG came around, though, it probably came too late for him to reap a rich harvest from it. He was old and stuck in his ways and he started pushing close associates away, because of it. And all those adoring fans rewarded him with much more love than money. Whether he was satisfied with that, who knew?
