Excellent article.
University / College education; unless a person is older with an established career or otherwise not needing to convert what is learned into useful and marketable skills, should be used to learn the things that will serve you into the future.
I've known numerous people who spent 4 years at school, learning subjects that, while interesting, is not something that can be converted to a useful skill.
The worst are those that learn how to be social justice warriors, where the only prospects from school are to be professional protesters....
That is true. I think its entirely related to one's potential to pave their way to future. If a person with high knowledge in a certain field cannot apply it to change something or to make a difference, that knowledge gaining is vain. But a person who learns for and to impact the society in a positive way defines worthiness of his knowledge.
Knowledge gaining defines the ability to have a diversified view of something or someone and implementation of this view to analyse and converge it to some meaningful result. So knowledge can be gained either by going to learning institution or by facing the real world and both have its own benefit.
