Shock collars could be equivalent to old-timey racism where e.g. certain races weren't allowed to use the same water fountains/bars/buses as other races.
Modern racism is much more subtle than that.
So people would dismiss shock collars as a metaphor for segregation, and walk out of the movie all like, 'gee, it's sure nice that racism is illegal so it doesn't happen anymore!', in the same country where black people have worse access to education, jobs, commit more crimes (gee, I wonder why people without education or jobs would try commit crimes for a living, no correlation there), are arrested for drug posession more often despite possession rates being actually similar for white and black people, are officially profiled by police (Stop and Frisk? anyone), have higher AIDS infection rates, are generally poorer and homeless at higher rates, list goes fucking on - but hey, they can vote and sit on the bus, and we have a black president now! Racism's over, everyone!
