I came to the same conclusion (based on my own experience in teenage, and observations later) that there is a lot of talent waiting to be tapped in teenage years, and treating teenagers respectfully as young adults and giving them responsibility is good for them and good for society.

That is one of the reasons we like to hire 17 year olds in Zoho and combine education with work. Labor laws won't let us hire any sooner, but if it were my own family members, I would hire them sooner.
