Going to school in the US from the mid-90s into the 00s we weren't taught that there were any world systems at all in our classrooms. Every action was created and maintained through sheer individual will and intelligence alone. The people at the top of the social structure were merely the ones with the most of that drive, and that is why they are at the top of this meritocratic order and have all the money and power.

So when our teachers and parents left us behind or neglected us and then attempted to placate us with sugar, anti-depressants, adhd meds, and screens it was an individual failing and not the evidence of a sick society that turned mass child abuse and ignorance about it into another capitalist profit industry.
