In our district, they have the salary. It's the other traits listed that are lacking. Education degree != engineering degree.
Our science and math departments are full of "Science Education" and "Math Education" degrees; NOT real scientists or mathematicians! Why not a B.S. in Chemistry? Because they can't take and pass the classes for REAL scientists. They run to the education department, get a whole new set of classes (and professors, btw).
I agree - the salaries SHOULD be high enough to attract better, more intelligent teachers; and they ARE that high in our district (again STARTING salary for all teachers with a BA or BS is $63,000!). Of course education degrees are REQUIRED - that keeps the ACTUAL professionals, many with advanced degrees, out of the compe ion for teacher's jobs. Once they have those jobs, also, they are nigh untouchable. Our district has been shrinking for a couple of decades (from 3800 students in '90 to about 2100 now); but the district isn't allowed to shape the makeup of teachers fit what is needed to teach the students. If a bunch of English teachers retire, but no Coaches do? Can't let some PE teachers go to hire English ones; now you've got a six figure salaried wrestling coach teaching English Lit!!!
My daughter currently has a Home Economics teacher "teaching" her Algebra, and a Visual Media teacher teaching her "History". Both of these individuals make of 90K per year; both classes are a joke.
The problem is NOT money; it is systemic - and varies from District to District. In some, as RG eloquently points out, it IS money; in others it is bad priorities - in ours, it's ed up DESPITE the fact that we currently are paying 17 grand per year per student to educate our kids. The big mask here is that SO many of the students are children of professors (15 thousand student university in a 30 thousand population town) - those kids succeed regardless. They also get good enough test scores, and provide a steady stream of IVY league and other elite post-secondary success to allow the district to feel elite, even though it's actually a wasteful disaster. I could simply blame the union, but it's deeper than that, the school board has never actually held the line on the CBA to even MAKE the union strike; they simply pretty much cave every 4 years to whatever demands the union makes. This summer it comes up again; we'll see where it goes...
