Kids now days will only put out what is demanded of them, if that. The big problem with that situation is that parents no longer try to parent and are more interested in being the kids "friend", and most friends don't demand anything of each other for fear of losing a friend.
If the parents won't demand their kids do something how can we expect that a school would be allowed to demand they do something? We can't, and plenty of parents will go up to the schools and defend their kid not doing anything if the school calls the kid out for lack of effort.
Now it isn't about education any more, it is all about money. Having kids butts in the seats everyday means the school district will get federal money for each kid each day, and schools like having money to spend on things like sports fields. We have high school sports stadiums here in Texas that cost in excess of $70 million dollars for one football field.
