My gift to industry is the genetically engineered worker, or
Genejack. Specially designed for labor, the Genejack's muscles and
nerves are ideal for his task, and the cerebral cortex has been
atrophied so that he can desire nothing except to perform his
duties. Tyranny, you say? How can you tyrannize someone who cannot
feel pain?
