I dont understand people who have a LOT of kids

Why people have more kids than the Replacement Rate (2 Kids):
* Selfishness. They want TONS of Mini-Mes.
* Lack of Common Sense/Breeder-Brains.
* Lack of sufficient birth control and or abortion.
* No regulation on multiple births (let's face it, people are having Multiples left and right).
* Religion (As you said, "Go Forth and Multiply").
* Peer Preasure.
* They never want to experience a "Empty Nest".
* Possible addiction to pregnancy and or childbirth.
* Sex can be quite delicious and fun for some people.
* The possible fact that they grew up in families of 3 children or more (IOW, large families).
* Failed contraception before, during, and after sexual intercourse.
and
* To ensure they get grandbabies (After all, only having 1 kid or 2 doesn't gaurantee grandkids).
