The deadwhitemaleness of school curricula and the YA canon

From the timeline, on that bird site, of Massachusetts poet Johnny Longfellow:

Try imagining all the public tax dollars that land in the coffers of the copyright holders of canonical texts. Then, you'll understand much of what underlies and drives toxic YA lit debates regarding which texts are deemed worthy of inclusion/exclusion within school curricula.

Imagine, too, the profits made by publishers who republish and promote works in the public domain for use in school curricula, minus any need to pay agents, authors, or their estates. So too, the profits made by those who create supplementary texts to accompany such works.

Yet, such factors are little discussed in YA circles, lest they distract from the seemingly well-intended and righteous topics of pedagogical practice, the inclusion of traditionally marginalized voices, and what values are transmitted to children/young adults via the humanities.
