When You Subsidize Something You Get More Of It

 The headline from the Daily Mail pretty much sums it up: "39-year-old mother-of-19 reveals she's pregnant with her TWENTIETH child (all with DIFFERENT men) and says she will keep having kids until she can no longer conceive - despite admitting she can't afford to support her family." I wondered if they all had the same first name and she just called them by their father's last name, but the article mentioned that she was not even sure who were some of the fathers.
