The problem is going to that there's going to be a large shock to the system. As pointed out in the article, a lot of teachers make $55k. So basically no education degree should be awarded because the average worker is better than a teacher.
Eventually the supply of teachers will dry up so much that salaries will go up. But how many years do you think until that happens? And then add 4 to when the supply catches up. Although I would bet what happens is that states no longer require a degree.
