The constitution and lots of arable land.
I kind of see us as a humongous two-year old. We're very egotistical and impulsive, but well-meaning and playful. We aren't afraid of real stuff that is dangerous, but we are afraid of the boogieman. We'll try anything once, especially if we're told we can't do it. We demand entertainment and want candy.
We're kinda cute unless you are holding candy we want or we accidentally step on you or we need a nap.
