I see your point , that ' s also a totally valid model . I don ' t know yet if I ' m going to release the source . But in the meantime you can check out the sample on the landingpage , that ' s pretty much the complete first chapter and shows the lexer . That way you can see if the code is something you ' d be interested in . <| sep |> Why would you think that it would necessarily be enough ? One of the big reasons private schools often do much better is the level of resources they can bring to bear and the fact they can pay teachers more and therefore poach top talent . The only people I ' ve ever heard throw around the oft used downplay throwing money at a problem are those who haven ' t seen the impact that scaling up and scaling down the money actually have . Another is the self selection of students and families that attend and the greater ease of kicking out failing students . They are able to have these resources by charging high fees , as well as through fundraising from parents and alumni . Now , some of these schools have tuition assistance for low income families . Some have tuition that could be covered or partially covered by a voucher . Your results are going to vary widely by school and area . The point is that these are the assumptions behind vouchers as pitched to the public 1 vouchers are going to give everyone a choice 2 vouchers are going to be most helping those who need to get out of failing schools 3 taking away money from struggling schools is going to force them to shape up because 3 b they really just haven ' t been trying till now apparently 4 private sector school saves money with better results . All these are often stated as facts rather than assumptions , and they need significant data to back them up . That data is far from certain right now .
