Deflation
Deflation occurred periodically in the U.S. during the 19th century (the most important exception was during the Civil War). This deflation was at times caused by technological progress that created significant economic growth, but at other times it was triggered by financial crises — notably the Panic of 1837 which caused deflation through 1844, and the Panic of 1873 which triggered the Long Depression that lasted until 1879. These deflationary periods preceded the establishment of the U.S. Federal Reserve System and its active management of monetary matters. Episodes of deflation have been rare and brief since the Federal Reserve was created (a notable exception being the Great Depression) while U.S. economic progress has been unprecedented.
American Empire: The Center Cannot Hold
When the Great Depression occurs, Burton Mitchel III is blamed in the Confederacy. In the U.S. which came out of the 1920s with a booming economy and with the Canadian revolt having been crushed in 1925, newly elected President Hosea Blackford takes the heat, with shantytowns and slums being named "Blackfordburghs". Millions lose their jobs, and in Utah, (under military occupation since 1916), a fanatical Mormon sniper guns down Governor-General John J. Pershing. When Japan and the U.S. go to war in 1932 after Japan is caught smuggling weapons to Pacific Canada (the occupied Canadian province of British Columbia) by the U.S.S. "Remembrance", and Japanese bombers attack Los Angeles. In the 1932 presidential election, President Blackford is defeated by Calvin Coolidge and his running mate Herbert Hoover in a landslide. However Coolidge is never able to take office. On January 5, 1933, he dies of a heart attack about a month before he could take office. (In real life, Former President Coolidge died of a heart attack on the same date.) Vice President-Elect Hoover assumes the presidency, practicing Coolidge's campaign policy of government non-intervention in the economy.
