Schools are bad because idiot kids attend them
Everyone in the film blames the teachers or the education system, but what about the parents? Kids who attend elite private schools and go off to Harvard come from good, educated families with parents who care and invest in their child's education....such as hiring tutors and reading to their children when they're toddlers.
Most kids who attend low-performing schools come from broken families with parents who don't spend time with their children, read to them, or give them every opportunity. These kids have no interest in education or schools since they have no support from home, so they don't learn at grade level and don't perform well on standardized tests. Why blame the teachers?
I blame the parents. Schools are "bad" when "bad" kids go there, not because the teachers are bad (although there might be some bad apples). Schools would be better if these kids had better role models at home.
