I still think this is a fantasy world. We all own computers. I doubt anyone here lives in a tenement. We can all type a full sentence with decent grammar. I'm going to make a fairly sweeping comment, but I think most of us are in a place that could do this for their families, or at least do the necessary groundwork to do the right thing by our children. But there are so many illiterate, uneducated parents out there, that perhaps had children at a very young age. And those children sometimes perpetuate the cycle. These parents probably think teaching is secondary to getting a meal on the table.
That's why school education is so important. Not every child comes from a stable home life.
