A few points have been well made, not all pupils are as academic as others and they need to have outlets for practical training or apprenticeships to interest them into a paying job.
Equally soe parents do mollycoddle their young rather than teach them independence and that is making a rod both for your back and theirs.
Start early, with small jobs around the house,garden,pets etc and then it's not a shock when you step it up in their teens.
My Grandchildren have gone through phases, but in general are helpful, generous of spirit and always grateful for what they recieve.
