I actually don't think so. Despite the doom and gloom from some posters here, I think the USA will be fine. Countries have an ebb-and-flow of good and bad times, and the US is currently struggling with a good deal of issues, but nothing that can't be fixed over time. The police force can be reformed. The health system can be improved. Minimum wage can be increased. Social mobility can be improved. Infrastructure can be repaired. And so on. I'm not pretending it'll be easy, but I'm saying the ship can be turned around.
I think the polarization, obstructionism, and the way many live in a post-fact world is the biggest problem the USA has at the moment, since it's such a major obstacle to everything else. It's like they're trying to get a car on the right course, and someone has the foot firmly on the brake pedal.
As for how exactly to heal the divide and move on, and re-establish a healthy social discourse, I have no idea on how specifically to do so. Except finally addressing the plight of the low-income population will probably go a long way.
The problem with that is that most incentives to that end still tend to be shut down as "socialism".
