And every major civilization has always....ALWAYS fallen. Looks like the people sounding the warnings, were correct.
How many times has it been said compared to the number of times it happened? That's the point. I can say "watch out, something bad is going to happen". Everyone will applaud when I'm right and promptly forget all the times I was wrong.
Every single time. The length of time that it takes for the fall to occur is the only question. The second that a large number of people start telling you there is a problem, you had better listen.
Well, you see, you are a prime example of the type of people that have the head buried in the sand. Almost all the scientists in world are telling us that we have a problem with global warming, but you refuse to acknowledge the cause of that problem. Now, if all the major people in politics and economics were saying we have a major problem, I would worry, but the are not. They say we do have problems with income inequality, but then outline solutions to that problem. And the various politicians choose who they think has the best solutions, then we choose among those politicians. A cumbersome system whose only defense is that it has worked better than any other system tried thus far.
So, do I think that we have problems to address? Yes. Are they major or insurmountable problems? No.
