What are they even being educated for?
Nobody cares about anything. Society is in a state of obviously rapid decline for the overwhelming majority, yet every change from our government has only accelerated the decline. These kids have no future. Society doesn't value educating them because they're feedstock for the capitalist meat grinder. Most of them will toil away in pointless jobs completely alienated from everything around them then die.
In educating the masses you will only teach them how bad a deal they have gotten and what steps may be taken to rectify it. They are more malleable and pacifiable stewing in their own ignorance. Decreasing education grows the lumpenproletariat.
