I agree with the author's premise that the current (US public) school model is not conducive for a child's future. The school's churns out students so they can be ready for JOBS (or get into a college that will help you get JOBS). It's been easy to fall into that trap with capitalism as the driving force behind everything. Capitalism has been evolving over the centuries, forcing workers into more specific disciplines then ever before (seriously, how many of us have 3 or 4 word job titles?).
However, that isn't to say structure doesn't have it's place. The author didn't to a good job of drawing some sort of line where structure is needed. A line is helpful here. That line should look like what we want our schools to ultimately achieve for our children and society. Are we a society of workers? Or do we want to be something else?
