Adultism.
There's clearly racial components to this story and others like it, but let's be very clear: this is the result of a society that doesn't value children, treats them largely like objects, and for sure doesn't care for their needs.
How can I make these claims?
There's a pandemic and yet school is still in session and in person. Did we reorganize society to protect the children? Temporarily, but when the economy started getting shaky, it was back to school for everyone so the parents could get back to work. Even if the claim of "not letting the children fall behind in school" is genuine, it's to enforce standards cultivated by adults for the sake of creating a certain type of person.
Are the systems deciding the fate of those people under the age of 18 AT ALL informed by those people under the age of 18? They are explicitly not. People under the age of 18 are there for the systems to do with as they choose. There is no solidarity with children or respect for their individual autonomy/consent.
And it's very easy to prove the systems don't care about the childrens' needs:
Humans have a finite set of needs. What are they? If you don't know, you weren't taught them. By systems designed to do something other than care for you and meet your needs. Any system dealing with children that can't produce a list of human needs is responsible for carrying a culture of adultism.
