Not sure how to comment on a general topic, but: One must be careful of blaming the poor for their condition, but there is no doubt that many poor people–as well some wealthy ones I’ve known!–have counterproductive habits and values which they should address if they want to provide decent homes for their children. (Cf. Oscar Lewis, “The Culture of Poverty” etc.) Wealthy ppl may be able to get away with expensive habits, drinking, wasting money on frivolities, but poor people have no such slack. So CASA can be of help in various ways.
