12 Years of Education = Minimum Wage?

In Canada, the first 12 years of education is equivalent to a minimum wage job which is a lot of years spent learning only to end up earning minimum wage. Couldn't we optimize this process?

Part of the problem is, of course, that the more people know something the less value it ultimately has in the eyes of an employer. If only one person knows how to count, then he becomes more valuable to the eyes of an employer looking for that skill. If a thousand people knows how to count, then that position goes down in value because the pool of applicants is bigger.

This suggest that part of the optimization of our educational system would require a degree of customization tailored to each child's skills (which will likely be possible with the introduction of A.I.). 

I'm certainly not suggesting that we should have 10 year old doctors... just that 12 years is a long time for someone not to get the skills necessary to earn anything more than minimum wage. The current process is only acceptable for a child growing up as they have a lot of times on their hands - something no human beings, at any other stages of their lives, has.

The temporary solution is for the students to take ownership of their education - to go beyond the basics and to start exposing researching career interests. It's possible for a child, for example, to be a certified programmer even before they complete high school. The courses are online for those that want to take advantage of them.
