You're close. Mongoloid is actually a now un-PC term describing someone afflicted with Down Syndrome.See: "one chromosome too many", referring to trisomy 21, as nicole said. Keeping with early Devo philosophy, I'd say this is a cynical take on gasp the de-evolution undergone by humanity in respect to society, either as a result of, or more like a response to the "Mongoloid" being able to assimiliate into society without anyone noticing.

In other words: we're all getting dumb due to lack of natural selection, and the Mongoloid is obviously what should not have been selected.
