Question[s] for people actually living in the US and posting on this thread:
The country is not a mess. One thing that non-Americans don't often realize is that most of our services are delivered by state and local government, not federal. Where I live in New York we have great schools, emergency services, police protection, public parks, etc. National politics are polarized, but have been before even more severely (think civil war, prohibition, neutrality before WWII, etc.). Our combative political culture is part of what drives us forward.
I love living here and feel perfectly safe here. There were neighborhoods in NYC I used to work in that I was cautious in, and was assaulted working in A&E a couple of times, but that comes with the job.
Food is cheap and plentiful here. We do not struggle, but DH and I both have professional jobs and are sensible with money. DH is also a very good long term investor. We own our home free and clear, have a nice pension pot and no other debts. Our biggest challenge with money is paying for uni for the two DC.
I have excellent health insurance through my job and the medical resources here amazing, if a bit overwhelmed right now. I have a couple of specialists I see and can usually get an appointment in a week or less. The last time I needed an MRI I got it the day after it was ordered. People come to New York from all over the world for the advanced medical care we have here.
Both kids got excellent educations. DS is now in his second year at uni and DD was accepted by several very prestigious universities and has just made her choice. She's supposed to start in the fall, but it's unclear at this point if she'll actually be on campus.
Life in the US isn't perfect, but it's often very good and I am very glad to be here.
