Species that fail to evolve in an ever changing world are doomed to extinction

The Soviet Union fell because centralized economic "planning" (sic) does not allow for creative destruction of inefficient economic processes. In a truly flexible society, individuals will migrate (physically and intellectually) to better opportunities. African Americans once fled the South for employment in the North. Today, that process is being reversed. Meanwhile, the middle class is abandoning California for states where they can earn enough to live. Human beings are they most adaptable species on the planet... unless repressed by other human beings.
