We're born wanting to suck on a nipple and afraid of falling and loud noises. More or less everything else is learned. And getting a job as, say, a grocery stacker doesn't seem exactly like an "unrealistic expectation" even for a kid with Downs. Your strawman argument is irrelevant. Even assuming that the supply of jobs is fixed, which it isn't (lump of labor and all that), here are the choices: a) overqualified person, here meaning somebody with an IQ of 100, works at a shit job and hates it; and person with Down's sits in basement watching YouTube all day and hates it, while society subsidizes his existence b) person with Down's does a monotonous job and is happy with it; and neurotypical person is unemployed and can choose how he spends his days while society subsidizes his existence I'd go for B, especially given that it gives the other person the chance to do something else useful. They may or may not actually do it, mind you, but at least there's a chance, while there really isn't in the other scenario.
