If the above is all true, that would prepare pupils for future jobs --whether self-employed or working a corporate job. One cannot run (successfully) a corner bakery without being able to handle routine and carry out mundane tasks or without getting up early and doing basic chores as well as being able to interact with others, keep track of your finances, etc. Corp job is much of the same. You're getting moulded to have the potential to be a productive human being. The alternative is to have people find out what works and not on their own. Even drugs dealers and macs know the importance of all the above. Now, sure some people for various reasons cannot conform and revert to more "chimp self" and don't do well in civilization. But even if they became foragers and lived off the land, they'd have to learn routines, have attention to detail, patience and so on.
