It's a terrible shame. I think the main issue is; philosophy instructs you to question everything, and schools want obedience, just like the workplace. It would go against their plan completely.
Generally, young people have such low attention spans devoting a good amount of time to a subject that never generates a clear result will also put them off.
I agree with you and you have raised a very important point. The world would be a lot better with more philosophers. We could rationally discuss ideas without offence!
In particular, I think that the rebellious spirit that we may have can lead us to the glory of building our own interesting philosophy to create revolutionary movements, however obedience based on a traditional education is boring and does not transport us to the search for knowledge so valid within the revolutionary character that philosophy gives us.
I have been very inspired by your comment, I will really have to be more attentive to continue writing about philosophy and education, it really is inspiring and exciting. Greetings and thanks for your valuable contribution.
