I fear it may be worse than we know. I think the rot goes waay deep, and I do not think we recover.
1939? Feels like it, but there is no longer the USA for the rest of the world to depend on - we are like Rome in its final days: still looks good, but hollow inside.
I have read “The History of The Decline and Fall of The Roman Empire” by Edward Gibbon within the last decade, and it was enormously depressing to read, because that parallel is inescapable in so many ways.
