I don’t believe “tough males” can help just by being teachers. The best teacher would not be much more effective than the average teacher when placed in the inner city, so why would anyone want to suffer for nothing? They would not have broad support of administrations and parents. If they did , then there wouldn’t be these seriously terrible schools to work at. The classroom is just a symptom. A woman or average man could do the job better at normal pay, if she/he didn’t have to take care of juvenile delinquents who were just doing time and have to have seriously offensive students with no hope of correcting or removing them.
So , tenure is not helping or failing inner city schools because teachers are not G-d.
