I was fortunate to grow up in the 70s and attend a somewhat experimental elementary school. All the grades were mixed. We went from teacher to teacher each day for our subjects just like you do in high school or college. There was lots of art. You advanced by your skills and interests and could go beyond your grade level. Then in high school we still had lots of extracurricular elective classes, could come and go from campus, could schedule your lunch hour at any time (well my first year was this way). I took jewelry making and used gas torches and worked with gold and silver, for example. So I totally see the value in unschooling and homeschooling. I have no children so have no actual opinion.
Nowadays I'm interested in unjobbing. I'm not very unjobbed being that I do the 8-5 thing, but at some point I did realize that striving was unnecessary so I quit doing that. Careerism is a trap. I actually succeed better by slacking.
