In a word, no. The statement imples that the American Dream actually ever existed in the sense that Casey means. This is a rather naive view of history.
While I do think a crisis is coming, it will not be the zombie apocalypse. I have been accused of predicting hyperinflation. I have not. I am expecting 50% inflation over a number of years. But all of us "hard money types" tend to underestimate the power of the state and the Federal Reserve.
All Empires fail. But the process is long and drawn out and after the empire falls, the country often continues to exist --Spain, England, and Holland each had thier empire that no longer exists, but these countries continue to survive and even thrive.
So I disagree with Casey, but I found his comments interesting.
