"Consequently, recruiting more effective teachers for public schools will be much more difficult than simply raising salaries."

I agree. I have a friend that took a lower paying job because he could not stand the handcuffs that the administration placed on teachers. Stuff like you have to give people a 50% if they put their name on the paper, you can't discipline students effectively, etc. I also know many teachers at private schools that make less than the public school counterparts but would not switch due to similar reasons.
