Ideally, we as a society should support people who choose to have one or two children, prioritizing these families over people who have half a dozen or more children. But that's because in my opinion people who have dozens of children have something wrong in their heads. If you choose to have a dozen children, you better be able to afford to raise them all on your own dime.

That being said, I really dislike means testing of any kind so I'd be ok with a social safety net for the wackos and their unfortunate children.
