The dilemma here is that some students when left alone can thrive without having a safety net education regiment, while some may just play games all day and waste away. And perhaps some may get too specialized and lack other basic skills a standardized education would guarantee. I think if there is going to be change, we have to start looking into whether or not those things are true. Lots of kids are home schooled right? The data should be there.
If kids have to learn how to drive then they should do the driving, and school should just provide the vehicle. Can't learn to drive while sitting in a bus (but it's more economical).
