> What do you think happens when you provide unlimited free food to a population of rats?

1) No idea, I'm not a rat, nor do I have any expertise in the economic lives of rats. Have there been any studies that show this? I don't have access to many journals.

2) Do you think that humans have the same goals, aspirations, and survival behaviors as rats? Do you think they are so similar that given a cage and food, humans would reproduce until they all died out?
