Agreed =)
And that is an interesting experiment. But I want to know one thing: If the bowl emptied, would that end it there and then? If so, then what the participants did was smart for them, if not, then I'm shocked that the first person didn't take the enire bowl each time. Just wondering.
But I agree with all the points you made.
Personally, instead of something like NAFTA, I think Cnanda, the US, and Mexico should become a sort of North American EU. It would solve a lot of problems (illegal immigration, etc.) no?
