If the state were to implement KG One's solution, you would have tens of thousands of Detroit schoolkids flooding the inner-ring suburb's schools. I can tell you that this is something that the suburban parents would be none too pleased with.

Traditionally when a school district opens it's doors as an open district, the school gets overwhelmed with former Detroit schoolkids. These kids aren't used to being in a stable learning environment, and it leads to disciplinary and other problems. Also, the academic standards would plummet as these students aren't accustomed to a more rigorous curriculum. This happened when Redford opened up it's district to outsiders about 10 years ago, and there has been a mass exodus of residents ever since.
