Many people have tried to define science fiction. I like to call it the literature of exploration and change. While other genres obsess upon so-called eternal verities, SF deals with the possibility that our children may have different problems. They may, indeed, be different than we have been.

Markets - and the other great modernist cornucopian tools - are magnificent wealth generating machines, built ad-hoc, through trial and error, constantly fine-tuned and refined, tinkered, adjusted.
