The idea of the state having control over its education system is based solely on the founding fathers failing to enumerate public education as a power of the federal government. It would take a constitutional amendment to create national control of public education, and that's not going to happen anytime soon. That's because even though everyone in the country believes that we should provide free public education to all children we must A) stick to the constitutional verbage written by the founding fathers (who did not believe in national education--except for Thomas Jefferson) and B) localize control of what our children are learning.
Local control is one of those phrases that gets a lot of use and a lot of respect in education policy circles. This makes a lot of sense to me because funding for schools is locally based, so the control is locally based. Funding does come from the federal government, but the bread and butter of every district is local. States try to standardize things and streamline their programs, which creates this whole mess regarding teacher training reciprocity, not to mention high school education reciprocity.
But this is the reason for public education. Any nation's public education is built for a single purpose, which is to indoctrinate the youth of a nation with the culture of the governing class. However, because our national government is handcuffed from controlling education, the indoctrination includes the fundamental beliefs of the predominate culture of the state and in some cases even the areas of school districts. In America we created public education to perpetuate the idea of the American Dream (one's ability to succeed in "attaining the fullest stature of which (he or she) is innately capable, and be recognized for what they are, regardless of the fortuitous circumstances of birth or position). That is the only common stream in the education system--anyone can succeed (We might also compare this to the myth of the medals in Plato's Republic, but that's a story for another time). Our education system lacks a common thread because of the need for state and local control, breeding the indoctrination of state and local culture, not national culture. This organizational fault is part of the reason we see so much disparity between states and between urban-rural-suburban schools. Because the curriculum and teacher credentialing standards are different from state to state and district to district the education of students from one state or district to the next will be inherently unequal.
So ending this on a slightly different vein than I started, I would like to say a word about winning the future: it won't happen unless we centralize our educational system. It's the only way we can properly work together as a nation to meet the changing needs of the American workforce. But there are two reasons this will never come to pass: 1) Conservative interpretation of the Constitution and the difficulty of creating an amendment empowering the federal government to provide public education and 2) America is not a 'melting pot' as much as it is actually a grocery store. Yes, there are a variety of cultures here, but they are--for the most part--compartmentalized into different regions and even different areas of cities and towns. Therefore the predominant culture within the district will beg/cry/fight for its right to push its agenda (strong words, I know, but it is what it is) on the children in its jurisdiction, and it will do so under the assumption that it is what the parents want and what they believe is best for their children--regardless whether or not it is what is best for the country represented by the flag to which they pledge allegiance every morning in the classroom.
