I know it seems impossible, that the cost would be to great, but think about the following. If every person capable of reading could, they would be more informed, more educated, and in a better position to stand up for their rights. If every child in a bad situation could slip into a fantasy world for a short time, it would make their life that much more tolerable. If every person starving for knowledge and the chance to be innovative had the ability to attain it, just think about how much better our world could be.
I just think providing that kind of opportunity to the people of our world would be a huge step towards creating a connected and openly communicative global society. I know that is an ideal which seems impossible, but why should we not strive for the impossible if that is what the world needs?
