I don't think it is that bad to be fair, just that there is much more focus on it than in the other superpowers. China and Russia are significantly worse in every way, but no one cares to talk about that. Considering that (like it or not), USA is the centre of the world and most of the information is created there, it is not surprising the focus on it.
Saying that, it clearly has some big problems, and the division on the country which seems to have started at the end of last century, escalated during Obama's presidency and got worse in the last 3 years is a significant problem. Hopefully, they have already fallen as far as they can and start fixing their shit soon enough. Don't believe for a moment that they are in a 'Fall of Roman Empire' scenario.
