The Effectiveness of Federal Government Spending on Education

I am going to keep this very short and very graphic.  Let us examine the relationship between federal spending on K-12 education as shown in this graph:

This graphic is from an entry posted by Neal McCluskey called Federal Education Results Prove the Framers Right on the Cato@Liberty blog.  He notes that there is no federal government constitutional power and then suggests that this graph of federal government spending on K-12 spending shows that spending to have no beneficial impact upon actual student learning.  Note the very flat test scores generally since 1970 and the huge increase in federal spending on education.  All that meddling and no result!
