The way the world works is that something negative always exists. That is how it has always been, and is always how things will be. New negative circumstances are happening every day, and the nature of human beings dictates that someone will always put some child down for their own benefit, even other children will do so. That said, you can't save everyone. No matter how hard an individual, or a group of them tries to, not every child can be saved, not every child wants to be saved, some children are just destined to be left behind.
No, I do not think that we will ever live in a society where no child is left behind, because there are always children that are not noticed. It is not that we do not care, it is that we do not find the children, or that we do not know how to serve them
It should be the objective of society to see to it that no child is left behind. All children are precious, and neglect of children is is society's greatest short coming. I think we should do everything we can do, but this will always fall short of everything we want to do.
Whether it be education, children getting enough to eat, or having enough clothing. Our society seems to make children pay for their parents not having enough to offer their kids these things We also put these people down on top of it because we are so much superior than these families. Of course, most of us know it is all about greed, as to why people have to endure such hardships.
I suppose it is possible that we could potentially create a society where no child is left behind, but I know that won't be happening during my time on this planet. I think there are too many issues that go unaddressed in our country and our current society. Children will continue to fall through the cracks.
