How strong parenting make the future of a child bright

I'm not sure what you mean by strong parenting, however a bright future on the child, doesn't merely depend on academic qualifications. It is also to make sure the child is a happy, and helpful citizen too.

For example, if a parent is teaching a child how to drink, that won't end well.

If the parent is physically abusing the child, the child could suffer from mental health issues, become and abusive person  and resort to violence in the future themselves or it could lead to self harm, and a negative way of seeing the world.

If the parent is supporting the child, helping them follow their ambitions, then the child will probably have a bright future.Allosing  the child to depend too much can also lead to problems.
