I think reemergence of segregation (our society is becoming more and more spread apart by race), the media being more corporate controlled than ever, multinational corporations which have no interest in our country having lobbyists (look at big oil), and our leaders slowly taking away our rights (look at patriot act), is just some examples of why are country is dying. Not to mention the NATIONAL DEBT AND IRAQ. What do you all think are reasons why this country is dying? Or hell, i'll even flip the script, what are some reasons why you think our country is getting better?

The corruption and rot of the two party duopoly and the lack of genuine non-conformist politicians.

The American people.

I agree that our political system leaves much to be desired (to say the least), but it's quite a jump to equate this with the death of America.

We will eventually cease to exist as a country, every one of us will eventually die, this is reality. In a manner of speaking, we begin to die the moment we are conceived. The same time and aging mechanisms that turn us from zygote to person are also responsible for our eventual deaths. You could say the same about America, that we "began to die" as a country when the first settlers set foot on the continent.

Personally, I think the end of America is quite far off. Let's not be too pessimistic here, government and social problems are not unique to us, nor does it mean that our country is dead or dying.

To answer the OP though, I think complacency and intentional idiocy of the American people are to blame for the problems you mention. There are other causes, but I believe these things are at the root.

The death of America as a nation may be far off, but the death of the ideals its based upon...well that is closer than some think IMO.

We are victims of our own conspicuous consumption and consumerism.  It is why we admire Britney Spears and Paris Hilton, the epitome of deep seeded cultural ideals. Those who were great and important do not matter.  What a sad story.  Americans are going to die being cheated out of their dreams never knowing that there was a whole different world out there to choose from.   :'(

Stupid Americans... *Said in a French accent* Cry me a river. 

Our problems started when people thought it was a good idea for SOME to make social, economic and political decisions for THE REST.

When people defined "familiy values" and a "good childhood" or a "healthy lifestyle". When it became the right of government to decide what I eat or what I wear or what I play when at school on the playground.

THAT'S when things went down hill...

That's not necessarily a bad thing. As enlightened as they were, the founders saw fit to legitimize slavery and deny women the right to vote. Things change, it's not always a bad thing.
Personally, I'm very happy that the ideals of only white men voting and people being allowed to own each other have died here.

I don't mean to discount the problems we are having, but viewed from an objective, rational perspective, many aspects of life in America have improved drastically since the founding.

Now, if you feel it's a shame that Americans seem willing to part with their freedoms on a very gradual basis, I would tend to agree. The outlook isn't as bleak as you suggest though, IMO.
