The main problem with teachers is that the price for them is not controlled by quality. A teacher who performs better than other teachers (e.g. a 10x teacher) will not be worth more in the current system. And with the quality/price relation missing, there is nothing a teacher can do about the price, and consequently their wages will be as low as possible.
Quality is hard to prove. Everyone thinks they're "quality."
The fact is most people are average. We freak ourselves out about these very few super teachers or super devs but most are not these people and they still need jobs and perform valid functions.
Even at the high level, teacher salaries aren’t very high compared to industry.
Couple that with high licensing requirements and bad working conditions, neither of which are secret, and of course the best and brightest do not consider it a real option.
