I'm saying that if you pay teachers a salary consistent with an MIT grad that was able to FIRE, that you will attract people solely for the money. If we are compensating teachers at 4-5x the median salary, then I would gladly quit my job and become a teacher even though I have no real interest in it. I believe that the best teachers enjoy their jobs and are not just looking for the money.
Now we could use a performance based pay system that could pay teachers more. Some of those systems fail to capture the right metrics. All of them are opposed by the teachers union. I think a slightly below average salary (factoring in benefits which are not typically seen in industry) with the potential to make more than average based on performance would be a good system.
