I taught in Oakland, CA thirty years ago as a substitute, so I saw a variety of schools. I saw the corrupt administrators in certain schools effectively diverting funds for things like special education by hiring their friends for the well-paid jobs like special ed and resource specialist and then calling a substitute (me) to actually do the job. And that isn't saying this always happens (I imagine the smaller suburban schools with people involved would have less of this). But the existence of these special programs present a great opportunity for graft and so there's incentive to avoid making special education at all efficient.
