UPDATE: For those who took offense at this graphic know that as I saw it the teachers’ drinking was a result of the cycle, not the cause. I interpreted this graphic as a slag on parents (myself included). If you are a teacher and were offended please accept my apology. If you are a parent and were offended – go volunteer in your local school. Regular readers will know that I have nothing but the highest respect for teachers.
One simple graphic from the always brilliant Jessica Hagy untangles the whole complicated mess.
