Final answer:
Following the Great Depression, the United States experienced the most rapid economic recovery.
Step-by-step explanation:
Following the Great Depression, the country in which economic recovery occurred most quickly was the United States. While Europe and Asia faced reconstruction and financial catastrophe after World War II, the United States emerged from the war with full employment, new technologies, and dominance in banking and international trade. The American dollar replaced the British pound sterling as the world's standard currency, and US companies spread rapidly across the globe. By the 1950s, the majority of Americans owned their own homes, and the United States became the world's leading manufacturer.
