The TLDR summary: "Blade Runner" comes from another SciFi dystopia:

> Universal health care has been enacted, but in order to cull the herd of the weak, the “Health Control laws” — enforced by the office of a draconian “Secretary of Health Control” — dictate that anyone who wants medical care must undergo sterilization first. As a result, a system of black-market health care has emerged in which suppliers obtain medical equipment, doctors use it to illegally heal those who don’t want to be sterilized, and there are people who covertly transport the equipment to the doctors. Since that equipment often includes scalpels and other instruments of incision, the transporters are known as “bladerunners.”
