I guess if you omit the civil war, ww1, ww2, the great depression, the financial crisis of 2008, racial strife, 1970s stagflation, and any number of major disruptions from the historical record, youre right.
I meant in recent years, but the 2008 financial crisis was nothing in the US compared to what it was in Europe. The US Dollar was never at major threat of collapse the way the Euro was.
