My post will get 100% ignored, but the administrative swell came from schools going from institutional models to customer support models, compounded with disability laws.
1990 Principal: "You're kid is acting like a shit, he's earned himself two days of out-of-school suspension. Come get your kid before we drop him off at the corner... *click*"
2020 Principal: "Good afternoon Mrs. Karen Fuckface, little Johnny's behavior manifestation came out during recess from being overstimulated. He bit five kids, smeared fecal matter on the walls, and hit his teacher Mrs. Grouch with a chair. We checked his IEP folder and saw he has five out of six main disabilities, plus a 504 to do 1/10th the work and given a minimum of a 50%. We have our school guidance councilor on the line for any assistance and care. Our dean is here as well to babysit your turd. This is his 3rd teacher after the previous two had mental breakdowns and resigned. We're here to kiss your ass because if you complain to anyone above us, all hell fire of retardation will fall on us all from the morons elected to our school board. Have a wonderful day!"
