Could you elaborate? There are at least 2 interpretations of “over-educated” people being a threat to “the system”.
Overeducated as in having university degrees and being “highly skilled” which demands imports of “unskilled” workers which causes integration problems.
Or overeducated as in understanding how “the system” works and are aware of the class war they were thrown in since their conception, how the system pits the working class against each other while the ruling class enjoys a paradise.
