The Panic of 1907. Black Tuesday (1929). Black Monday (1987). The Great Recession (2008). The Flash Crash (2010). Taken together they tell the story of a nation reaching enormous heights of financial power while experiencing precipitous dips that alter and reset a market where millions of Americans invest their savings, and on which they depend for their futures. Nations blends economic and cultural history to show how each of these major crashes provided painful lessons that have strengthened us and helped us to build the nation we know today.
