When inequity is low and opportunity is easily available, peaceful, moral decisions are preferred and Aristotle's "Good Life" is possible (Americans call the good life "the American Dream"). Opportunity created the simple inspiration and genius of the Mayflower Compact, for example. Post-World War II and the post-California gold rush 1850s exemplify times of great opportunity and low inequity, and both resulted in unprecedented technological and industrial advances. On the other hand, 1893's global economic panics were not met with sufficient wealth-distributing government policies internationally, and a dozen major revolutions resulted, which some argue were significant causes of World War I. Few would argue against the assertion that World War II began in response to the economic strictures of World War I's Treaty of Versailles and the failure to create government policy that supported economic opportunity during the Great Depression.
