I kept going back to this tweet because it is surreal.

It is a teacher job fair at the University of Michigan.

The tables are around the room, staffed and ready to hand out fliers to prospective teachers.

But the hall is empty.

There are no prospective teachers.

Thanks, No Child Left Behind.

Thanks, Race to the Top.

Thanks, inventors and promoters of VAM.

Thanks, teacher-bashers.

Who will teach?

Oh, right. Computers.
