We could start by getting rid of our borders, and open up our markets to real, free global trade, and give other poor countries a chance to compete, like China and Mexico, who could really use a helping hand. And change our flag, to something more accepting to the world, something like a United Nations theme, while still keeping some independence if we choose.
Ah, I get it. And just like Breyer and O'Connor said yesterday, we should (or will) take other countries' laws and traditions into consideration, and make our laws cooperate with theirs, but no worry, we'll still have "a" constitution (of sorts).
