Futurismic, in fact. See this article by Cory Doctorow.
But also note these points Doctorow makes:
Lapsarianism — the idea of a paradise lost, a fall from grace that makes each year worse than the last — is the predominant future feeling for many people. It's easy to see why: an imperfectly remembered golden childhood gives way to the worries of adulthood and physical senescence.
Running counter to Lapsarianism is progressivism: the Enlightenment ideal of a world of great people standing on the shoulders of giants. Each of us contributes to improving the world's storehouse of knowledge (and thus its capacity for bringing joy to all of us), and our descendants and proteges take our work and improve on it.
There's a thought here - these are the ur-myths of conservatism and progressivism. Now, I'm engaging heavily in my own prejudices here (and more than a little from TV and pop culture rather than memories), but in my very limited experience, there is a correlation between the conditions of childhood and later political belief.
If you were bought up in an idyllic world where you were a special little prince or princess and everybody catered to you, in my experience, you hit high school and become an asshole. A jock. A frat boy. A heather. And if you don't grow out of that, you wind up as a conservative. Everything has gone to shit since people expect you to take responsibility and perform, and nobody seems to understand that you're a Special Little Snowflake AS OF RIGHT. You're mad because somehow, someone has taken away your place in the world.
If you were bought up with a low grade shitty childhood (and I was, as were far too many of my friends) then you realise quickly that the world is unfair. I'm not talking about the real nightmares of abuse, I'm talking about the fat kids. The geeks. Those who didn't fit in, who stuttered, who had weird hobbies, who moved at the wrong time and never quite clicked into place in their new social jigsaw. And so you develop empathy. And when you start getting into high school and then the real world, you realise that you can change. People can change. By taking responsibility, by growing, you can become better. Things can become better. That people have the ability to overcome, and that one of the best things in the world is helping people realise that ability.
So I'm speculating that the ur-myth we accept might be based on the trajectory of our lives - whether we find ourselves thrust out of some Eden to get by as an adult in a cold hard world and mad as hell about it, or whether we find ourselves reaching for our potential by overcoming our pasts.
Or perhaps I'm just masturbating in public again. Kara Thrace does that to me.
