I think you meant massive anti-federalism.
If we had a federal procurement system for math and english textbooks, after being put out for a nationwide bid, the per-unit cost would be about 10% over the cost of paper and printing. (the 10% premium is the bid adjustment for a women or minority owned business)
Now $8 textbooks wouldn't save a lot of money compared to the national education budget, but it would be a good start. And do we really need regional variations in math textbooks?
