> Educate the parents instead to spend more right time with their children.

This is kind of assuming that the parents have full control over the lives of their children. Which:

a. Isn't true b. Shouldn't be true (because some parents are bad)

As a parent you go to work for 8+ hours per day. During that time your child is in the care of "society" (school / daycare / whatever). And during that time the only thing that protects them is laws and regulations.
