It’s not a new topic for me, but here’s more reason to simply abolish them:

The education sector is notoriously ineffective at identifying high- and low-quality workers, making it difficult for the labor market to penalize students from education departments that produce low-quality teachers. The culture of low standards in education is partly to blame, as those within the education establishment have shown little interest in distinguishing good teachers from mediocre teachers, but why can K-12 schools get away with not distinguishing high-quality workers from low-quality workers? What makes education different?

Two words: teachers’ unions. As that famous report noted three decades ago, if a foreign entity had imposed on us this educational system, it would rightly be considered an act of war. What should we think about the domestic enemies that have done, and continue to do so?
