It's worth pointing out that wages in the US are vast compared to other developed countries, though, too. We outspend OECD by 35-40%, but our average national wage is also higher than OECD by 35-40%.
Labor compensation in the U.S. is also extremely unequal, which pulls the average up in a way that isn't very informative as to this particular issue. The average starving PhD would be a much better and more knowledgeable teacher to high school students in the subject she took her PhD in, than the typical high school teacher with nothing more than an Education credential. Are you sure that you need to pay such high wages to existing teachers?
