Why do parents....?

Why do parents allow their children to keep a pacifier until the age of 5!?!?! I work in an emergency room and I see children constantly. They look way to old to be walking around with a pacifier in their mouths and diapers on. Half of them don't have shoes on. Also, these kids are running around like monkeys! Hello....please parent your children...Thank You!! I just can't believe how sad people have become!
