Nice cheer from a knowledgeable crowd . <| sep |> Is in UK . I ' m sending mine back i bought a few days ago and ordering another . c o n f i r m s v i v e b l a c k f r i d a y d e a lsforukincludeshppcbundle <| sep |> What did you make ? <| sep |> Two points 1 . Sure , the sample of students is selfselecting and biased . But when government forces you to put your child into a school depending on where you live , this also creates a selection bias . 2 . Whatever way you play it , you ' re advocating to lower the average quality of education right ? You ' re essentially saying you ' d feel better about the situation if betteroff kids got a little worse educated thus reducing the difference to kids in public schools . I ' m sure you see how this isn ' t the best position . You cannot blame a parent for having their child ' s best interest at heart . What ' s essentially needed is a lot of resources for public schools to make up for the lack of parental care poor kids experience .
