The U.S. was never intended to be a democracy; it was designed as a Republic.
The Rule of Law (the U.S. Constitution,) was crafted to "bind down from mischief" the Rule of Man. Nevertheless, two centuries later the Rule of Law has been subverted completely, the Constitution is now meaningless, and we find ourselves living in a Fascist dictatorship run chiefly (though not solely) by Wall Street. A quiet coup d'etat has taken place over the span of many years and decades, and ours is an occpied country now.
Even so, American fascism will ultimately fail and collapse. It is inevitable. Too much debt, too much misery, too many structural problems, and more Black Swans waiting in the wings than AmeriKa can possibly hope to survive.
It's hard to say what the next chapter will look like, but it will be Hell on wheels, I'm sure.
