"if you can read this thank a teacher" is a classic car sticker. However, in England and Wales, we have half a million of them (in a population of about 55+ million) and the turnover is estimated at about 9% per year (some of that is family break teachers leaving and returning). All teachers in UK have to have a national curriculum related degree... The Normal Distribution being what it is (and wage rates not huge and currently frozen) there might be quality issues ahead. What about US?
