The education system discriminates against auditory learners.
Whether it's reading, taking notes, homework, quizzes, or tests, virtually everything we do in school is primarily visual. Visual learners clearly have an unfair advantage over auditory [and tactile] learners.
A couple years ago, I went to a psychologist to be tested for ADHD, due to parental pressure because I was having a lot of trouble focusing in school. While I was there, I performed numerous cognitive tests. The results: my auditory processing was in the 98th percentile, while my visual processing was actually below average! This stunned me. I had an epiphany-like moment. The inability to focus wasn't the problem, it was merely a side-effect. The fact the education system is so geared towards visual learners was the true problem!
I believe we should reform the education system to be more flexible, and therefore more supportive of auditory/tactile learners. In fact, I believe this would drastically cut down new cases of ADD and ADHD, considering many children are misdiagnosed with these disorders simply because they are poor visual learners.
