Ordinarily, I would say that any money given to any public program should have some oversight. We all know what happened to the bailout money Bush gave the banks and lenders...they gave a lot of it to themselves! However, regarding public education, I wish the feds would butt out and let the teachers teach to subjects, not tests made up by non-teachers. There are too many strings attached to Federal Aid to Education and they make the process much worse...not better! States are closer to the problem and should also return much of the control to the school districts.How might the states be affected if there were no federal control over public assistance programs?
Isn't it already the case, though, that some states have much better systems than others?
