"Every offspring of individuals with citizenship status belonging to this species, as long as they can pass the birth test, automatically gain citizenship. Such species are classified as middle-class species."
Niu Ma explained.
"What about the upper-class species?"
"All individuals of the upper-class species automatically have citizenship status, and they won't be stripped of it even if they're unemployed. Individuals who fail the birth test aren't sent for processing; they're euthanized instead. Moreover, if relatives are willing to pay a hefty fine, the individual can continue to live, but will be demoted to a third-class citizen."
Niu Ma said.
"Worthy of being an upper-class species. So, which species belong to the upper-class?"
Liu Zheng asked.
"I don't know. I'm just a delivery guy, where would I meet anyone from the upper-class?"
Niu Ma rolled his eyes.
"Alright. Then why are humans classified as a middle-class species?"
