This has Groid Fatigue written all over it. Why a sudden increase in illiterate 3rd graders? A THIRD of them???? Sounds like we've got a problem with substandard intellects, single parent(s) with substandard intellects, turd worlder invaders, and lazy/stupid multicultural experimentations taking the form of "teachers".
I'm proposing two solutions. Direct taxation on the families of the deficients and segregation. Why should the smarter children whose ancestors have perfected instructing their young have so suffer through the exposure to this garbage?
