We can teach our children both. We cannot know the future of our children. We can teach our children to be a successful employee while teaching them to also to be business minded. While you are an employee you can be a businessman as well. We need to explore our mind not to focus only in one field.
I think that also in order to be a successful businessman, one must also experience being a hardworking employee. So that in the future, when a child reaches maturity and have his own business, he will also know the value of working hard and also treating his employees very well. A good business can be possible with the help of hard working employees as well.
