This feels a bit out of touch. Firstly, anywhere in the USA, even Mississippi, is richer than almost anywhere else in the world in dollar terms. That is always going to buy a certain level of function and safety compared to most countries in the world, which are, well, poor. Next, "the US" is continent-sized federation. Vermont, say, is clearly safer and more functional, by any measure, than all but handful of independent countries.
In terms of figures, the USA is currently #43 out of 105 in the Safety Perceptions Index. Admittedly not a great score (but I can't help noticing that #1 is Uzbekistan, which is a literal police state). Even harder to measure "functional" but the US is at #20 out of 193 in the Human Development Index, which measures wealth, education and healthcare.
Whatever the current frame of mind of Americans, it's important to remember that the USA remains a privileged place.
