I think if they want to have these children, it's their right to do so. As far as I've read, they don't receive any type of assistance. They take care of themselves and others, from one of the episodes I watched recently. (When they and another family went to design and build on to a house of a large family).

Since when is it anyone's business to tell someone how many kids they can have, especially if they take no money from taxpayers? If it bothers you so much, how about going into the projects and telling these woman that have all these kids by different daddies to keep their legs together... after all, we the taxpayers are paying for those babies.
