the point is to take students who's parents care from bad schools and put them in an environment where they can get a decent education.
Its not always about level of care the parents are providing but what they can provide. How much care towards education can a low-income single parent working two full time jobs provide?
What is the parent doesn't have a great education themselves and aren't able to help their child academically (and only motivationally)?
Should that child suffer, not only because of that, but because of dwindling resources in the public school system that are being drained by the charter schools?
The students who are struggling are the ones who need the best resources/teaching/etc. If charter schools are as great as they are made out to be - they should be VOLUNTEERING to take students who are struggling academically, not shunning them like lepers.
