The reason why the state got involved [in hasidic education] is because of the extraordinarily high [number] of welfare recipients in the hasidic community. This is [partly] a result of large families, but mostly [a] lack of basic education… [This is] about communities that refuse to give their children any secular education that will prepare them to enter the workforce, receive higher education needed to achieve and contribute economically, or even to interact with the wider population… [As a] result, [the hasidic community denies] their children basic social and economic opportunities and condemns many of them to living on welfare.
