I don't think it makes sense to pay teachers more on average.
But, you have to factor in the whole picture. If someone just has a bachelor's degree, they get the summer off and a large amount of vacation time, pretty normal and decent hours, they get good benefits and tenure, that all factors in. So, it's really a range. For a teacher in South Dakota fresh out of school, $40k might be perfectly reasonable. For an experienced teacher in New Jersey who has a masters in chemistry, is on a professional development committee and coaches football, $100k might be reasonable. But, this idea that we should increase all teacher salaries by 50%, that's bonkers.
At school from 7am to at least 4pm, and perhaps later if they coach or sponsor any extracurricular activities or clubs. And then they get to go home and grade papers and prepare lessons. Teachers don't work any less than anyone else and they work more than a lot of people in other professions.
