Mathematically more of those parents win the lottery and the schools keep doing wellI ' m not sure I understand your argument here . Could you clarify it please ? Are you alluding to a confirmation bias where because parents believe a school is good more of them apply to it which makes the school more sought after ? Nope , you ' re putting words in my mouth . Ok , I might have . I thought you were arguing against privatecharter schools in general and advocating their elimination . With regards to your other points , I tend to agree . This all boils down to two simple truths 1 . There are parents who , for a multitude of reasons or none at all , just don ' t care about their children ' s education . There are of course also parents who , for socioeconomic reasons , can ' t afford to put their child into a privatecharter school . 2 . Government will provide the service of education to those who don ' t have a better option for whatever reason . But , whenever you ' re in that situation , it ' s unrealistic to assume you ' ll get a great service . This applies to healthcare and transportation too for example . Those who can ' t afford a car take the bus . Those who can ' t afford health insurance get medicaid .
