There is more to life than $$.
Perhaps the talents, desires and goals of said student lie more in line with what a trade school can provide.
Providing as many paths as possible is a good thing is it not?
Perhaps, although at the age of 16, I'm not sure how much we can rely on our knowledge of a student's talents, goals, and desires. Even developmentally challenged kids moderately into the autism spectrum can find new challenges, opportunities, and capabilities in a college environment.
I'm not arguing against training in the trades. The community college I teach at does a lot of training in the trades, as well as classes that broaden the mind. Why would you steer kids away from that?
