The whole problem stems from us prioritizing the species over each other. When we worry about genes or humanity as a concept, we miss out on the billions of people that actually matter. If we all choose to not reproduce, instead focusing on making the most of our lives, it'd be better than our descendants living enslaved by a societal machine till heat death. We think about the forest instead of the trees, when the former only exists for the sake of the latter.

The sad truth of capitalism is that not even the rich are in charge. The principles of accumulating power drive it, not the well being of wealthy families. If they escape the cycle and focus on their own happiness, someone else replaces them. It's power for the sake of power. Not even the dictator really matters, just their power.
