That is interesting indeed. There are so many factors that create barriers to success for people. Often, we have to dig deep into the past to figure out WHY people do what they do. Poor vision is a great example of this. If as a child you couldn't see the board, it's hard to learn. As a result, education suffers and you have to do SOMETHING to make a living. It's quite sad.

Thanks for sharing that info with me, and I appreciate the upvote. :-)
