Educators have their hands tied. We've centralized everything, and the central bureaucracy has decided it doesn't matter how innovative educators can be because the central bureaucracy already knows everything about the best way to teach, and if you deviate from it, you're fired. (A couple of intermediate steps through failing test scores and the consequences, but that's the effect.)

Until the educators get the central bureaucracy off their backs, it doesn't matter what they are capable of.

If you'd like to read my point as being that the central bureaucracy is "the most entrenched, hidebound, nearsighted, and even perhaps terrified of real change" part of the system, I'm perfectly comfortable with that.
