This is the way I see it - we should strive to come as close as possible to equal educational opportunities for all students.
The problem is that vouchers/magnet schools.charter schools, etc. only benefit those kids who have parents that are savvy enough and financially able to take advantage of such programs.
I don't think my kids should get a better public education than my neighbor's kids just because I'm smart enough to work the angles, or my job is flexible enough to allow me to take my kid to an out of district school.
It seems to me that too many kids are 'punished' because of their parent's actions or shortcomings, I don't think it should carry forward to the education system.
Therefore, my premise: we should strive to come as close as possible to equal educational opportunities for all students.
