Is school really needed after one becomes literate and learnes the basics of math and science?
Everyone needs to be educated to a fairly high standard because you rarely know what you REALLY want to pursue until Y10/Y11 really.
Also, better educated people = better economic growth woo!
I personally think that many schools are the most intellectually stifling things ever. They try to squash your identity into a fraction of a class, unimportant and just the same as everyone else.
On the other hand, schools are good for social interactions.
