I don't know much about the American Constitution, but from the little I know it's nowhere near perfection not even perfect enough for the Americans.

Well, just like almost every other law book of every other country, it seeks to uphold the honour of America, show off the strong foundation America rests on, it's hospitality towards foreigners, and the rest of it all, while doing the minimal least for the average American.
Laws never really work because they oppose everything the common man stands for, deprives him of everything he feels he deserves. Laws are made for Law, not for man.
