Is 14 enough?

Well I am sure all of you have heard about the mom who gave birth to octuplets a couple of weeks ago. Then it turns out she has 6 other children and she is single. She is on welfare and is unemployed. Then she pays 10,000 to get pregnant? 6 times? Oh and the news gets worse, ( I am not saying having children is bad news) but she gets pregnant with 8. How is she going to afford that? Why would she want more that 6 children, if she can't even afford them? Oh and she lives with her parents. I just don't get it.
