Back to the Economy
Money is really just an idea. More and more, it is becoming conceptualized rather than a physical asset as electronic banking is coming into play. So, what does it represent?
Money represents power. It represents your ability to gain assets, and it serves to show off these traits. It can be inherited, power given down from generation to generation. The same is true for the idea of survival of the fittest. Animals and plants inherit the ability to survive, to feed themselves, to compete from their parents. They show it off with mating rituals and the sheer act of flourishing.
Maybe we are not as different from other life forms as we make it out. We just have the added advantage of better cognitive skills.
Maybe, like we laugh at a cat staring predatorily into it's reflection in the mirror, other "higher" life forms are laughing at us for our the inability of our brains to see how the world really works. If they came along, I think we would still like the right to live.
