The word Mongoloid was originally used as a derogatory term for people of Mongolian descent in East Asia, but it was later used as an equally derogatory term for a person with Down syndrome, which is how it's used in this song.
The song reclaims the word, with the main character a proud mongoloid who is happier than most and has a job. No one even knows he has a condition.Mark Mothersbaugh of Devo
explained in an interview with Smashing Magazine
: "In the bigger sense of things it was questioning man's calling himself superior to all other forms. It was just calling into question the insanity of what our value system was."
He said that while some radio stations found it objectionable and refused to play the song, the band heard from parents of kids with Down syndrome who said their kids loved the song.
"They were happy to have a song about them," Mothersbaugh said. "It wasn't making fun of mongoloids. It was kind of questioning why the value system of humans is about going out and getting a job, just mindless toil."
