This would also have a supply and demand benefit for the people that become teachers. At the moment, a 'C+' average in high school will get you in to most teaching courses in my state. More money means more attractive means more applicants means only the better applicants get in - this means better teachers and a better system. (And I appreciate that smarter != better, even in this case, but if teachers rarely got 'A's in their schooling life how can we expect them to challenge and inspire those who do?)
