Gene Shaft
In the 21st century mankind was on the brink of destruction. Through genetic engineering however they eradicated such feelings as love and the desire for power. Since women are naturally less agressive than men, women to man ratio was set to 9:1. Now people are engineered to have skills that others view as being necessary.
