Separate but Equal? Philadelphia Charter Schools vs. Philadelphia Public Schools

As I sit here on a Tuesday afternoon, I am compelled to write about the injustice facing Philadelphia parents today and I'm eerily reminded of Plessy vs. Ferguson, the separate but equal case that governed our educational system for almost 70 years. Looking back at this policy, it is strangely quite similar to the setup we have in Philadelphia regarding business or private run schools (charter) vs public Philadelphia schools. As a parent of a special needs child, I am almost shocked that no one has thought to put these two ideas together, but I'll take a stab at it!
Separate but equal was deemed unconstitutional through Brown vs The Board of Education, but it seems that there is a new separate but equal that seems to slowly but surely creep up in this modern age.

Charter schools are a separate form of education that is deemed for everyone, but they are all run differently based on the business or private entity that run them. They have flexibility regarding who they hire and how they deliver curriculum to their students. They seem to be run on a totally different plan than district run public schools. Public schools have a set standard in hiring and delivering of the education to students. Teachers hired have to be certified (not always so in charter schools) and they have to follow carefully constructed criteria (IEPs, etc.) in order to comply and be able to obtain funding. Why are we treating these two streams of education so differently? They are both publicly funded school options for all Philadelphia residents. One appears to be better than the other. In my opinion, it appears that charter schools weren't asking for extra money or extra personnel to keep their children safe, but the public schools were. Why are repeating the same mistakes over and over again with regard to education. I thought the entire message of having charter schools was better access to education and to see if we could model all public education to work for all students. Not to separate them, but for them to work together bettering the education for all students receiving a public education which includes charter school students.
I almost feel like there is a set plan to blatantly shift or pull the wool over our eyes so that we do not see the injustice that is going on her today. As it stands, there is separate but UNEQUAL treatment going on in public education of the Philadelphia School system and NOONE, not even our Mayor is doing anything about it! It is deemed unconstitutional for a reason, and as parents we need immediate help to solve this situation. The discrimination has taken a left and shot right to hell regarding the education of our children here and unless we go further than the state (Governor is not interested in helping us) we will get nowhere. What are your thoughts regarding this modern day injustice?
