My wife, her sister, and mother in law work in public education. Lack of resources are a big problem but according to them, the major problem is parenting and these kids home life outside of school. Add in all the social media stuff that these kids are hooked on which takes away their focus. You got grown people who cant take themselves away from the phones, tablets, ect for five minutes. Imagine these kids at school. There is alot of blame to go around.
People will debate against teachers who are at ground zero of the problem and say its something else.
