I knew very little about what caused the crash, even though I'm 79, I found it very informative. I have children, and grand children who know nothing about it. I think this is something that should be seen in all our schools, especially with the recession we are in the middle of in Canada. I thought the documentary was well done. I'm sorry that they didn't deal with our present economic problems and how they relate to each other. It was good to be remember what life was like when I was a boy. My father had to line up every day to see if there was any work to do. I remember walking down the train tracks looking for coal so that we could get some heat in the winter.
