The Great Depression vs. The 2008 Financial Crisis
What They Share
Both crises followed periods of rising speculation (margin-fueled stocks in the 1920s; mortgage-fueled housing and derivatives in the 2000s), both triggered severe banking-sector stress, and both led to major new financial regulation afterward (Glass-Steagall/FDIC/SEC in the 1930s; Dodd-Frank in the 2010s).
Where They Differ
The 2008 crisis benefited from lessons the Depression taught policymakers: the FDIC (created in 1933) prevented the kind of widespread bank-run panic seen in 1930-1933, and the Federal Reserve under Ben Bernanke — a scholar of the Depression himself — moved aggressively with emergency lending and quantitative easing rather than tightening. The result was a deep recession, but a far shorter and less severe one than the Depression's decade-long drag, with unemployment peaking around 10% in 2009 versus roughly 25% in 1933.
