I fundamentally disagree. Things are getting better.
From the outside looking in, the US is going downhill in a number of ways. Some things are improving (like healthcare) but the changes are only a very small step with how far there is left to go.
It's... largely an improvement from eight to twelve years ago. Bush's bullshit (for lack of a better catchall term) on top of some economic confluences basically fucked us seven different kinds of sideways, and we've only started pulling back out of that crap in something like the last year or three. There's definitely a long way to go, but the slide downward has been mostly arrested, and is starting to pull back up in several areas. The ACA stopped a lot (if not all) of the downward spiral our medical system was seeing, we're pulling back on useless adventurism, the environmental stuff continues to see steady (if arguably not enough, but again, anything is better than nothing) improvement, the economy is starting to get back into shape (if, as SG notes in part, still seeing some issues), or at least moreso than it was a few years ago... we're even starting to pull our heads out of our asses on infrastructure maintenance, to a degree. Things really are just kinda' getting better, and is definitely better in most areas than it was when I was a kid, even if that slump in the middle of things makes it hard to remember sometimes.
There's definitely problems, but largely they're smaller ones than they were a couple decades ago. Arguably not as small as they
should be, but, well, we had some popped bubbles, a couple of wars fought on false pretenses amongst a host of other fund draining bullshit, and some fairly stupid decisions made in regards to things like taxation, so just that fact that the country's
not a bubbling molten crater is honestly somewhat surprising.
... also nosebleeds
can be normal, but they usually
aren't, and they're especially a possibly bad sign when you're already ill.
