> the differences between students will definitely not “average out” at this scale
Of course it will. Assigning kids at random will produce an average over time.
> how do you expect to handle poorly performing schools as a whole?
The teachers in that poorly performing school will have a powerful incentive to do better.
> Do you not expect the quality of teachers there to just plummet?
I expect if you dangle $20-30000 if they do better, they'll do better. Monetary incentives work.
And in businesses that pay commissions, the people who are good at getting those commissions (i.e. they're good at their job) want to be there. They're not satisfied with just a salary. High commissions attract the best.
Can you provide evidence of this? CEO compensation is a terrible model that encourages short term tricks like stock buybacks, front-loading revenue, and other tricks to garner short term performance. As for rank and file employees, measuring results is difficult … just like in schools.
> measuring results is difficult
And the better job of that a company does, the more profitable it becomes. Companies have a very strong monetary incentive to do an effective job of that.

Is it? Executive bonuses etc. at Boeing crashed along with the MAX crashes.
