> After 12 years of general education, how do you justify more?
A lot of the concepts you explore in university arts classes are things that a 12 year old just won't understand. Exploring subjects in a deep and meaningful way isn't possible until you've got your full adult toolkit of emotions and experience.
> In my opinion, we should be pushing specialized education at a younger age. When students exit high school, they should have skills that they can expand or fallback on. They can then use that fallback as a safety net to explore other options without extreme risk or debt.
How would you see that training going? I went to a rural school that had a graduating class of ~100, and there was little to no funding for extra courses - my choices of vocational training was comprised of "mechanics" or "woodworking".
