Things
are different in the city today. If your school isn't up to par, it gets a bad grade. That means the school's no good, and it isn't Mr. Bloomberg's fault at all. You see, this means we need to close or replace this school, until we shuffle kids far and wide enough that we can say we're making progress. And if the new schools don't work, we'll just rename and replace them.
If we do this long enough, no one will remember those bad schools we keep opening and closing. And when you get right down to it, the important thing is to keep those balls in the air, and perpetually give the impression you're reforming.
That way, you can keep the highest class sizes in the state, the lowest paid teachers in the area, the most overcrowded facilities in the region, and no one will think to blame you for anything that goes wrong.
It's your classic win-win.
