I love how you assert that with such confidence, as though you actually know what you are talking about!

You are getting dangerously close to personal attacks, which I believe will detract from your otherwise reasonable points. I think the discussion on HN is one of a few places where you could get appreciation for the problems in the educatiom system and it would be a waste to end it in heated emotional attacks.

No, it's just my speculation. It gets tiring prefixing everything I say with "It is my personal belief that"
