America is a very sick nation. I suspect that racism, mass killings, corruption, gang culture, the election of bad people to high office, drugs, extreme poverty, homelessness and all the other ailments it suffers from to a far greater degree than any other democratic nation in the world, are not individual illnesses but the symptoms of a deeply engrained malaise that absolutely refuses to respond to treatment. Most Americans who are aware of their country's infirmities blame them on the sins of the past. As with most nations, these sins are numerous but my guess is that they make America vulnerable to infection rather than being the illness itself.
What is the virus that courses through the veins of the United States attacking every part of its being, laying it low in wave after wave after wave?
I'm not a doctor but I think it may be hubris.
