I am not surprised that teaching ranks so low. Much work in this profession, such as preparing lessons, grading papers and attending meetings, is done after the school day has ended.
Teachers spend long periods of time on their feet.
Working with rambunctious children can be fatiguing and stressful. In Pinellas County, for example, nearly 80 percent of the instruction staff is women. In the elementary grades, the percentage is even higher. Men do not teach at some American elementary schools. In early America, before the government institutionalized the profession, nearly all teachers were men.
