Teachers are sort of faced with a thankless task, because no matter how good they are, unless they find a way to personally rationalize the rewards of their effort, nobody else is really going to do it for them en masse.
I came from a poor family, so working and going to school at the same time was natural. It taught me multi-tasking, although we didn't call it that back then. I learned I could never be idle, I need to be doing many things at once.
