The Great Depression of the 1930s is a classic, albeit extreme, example of an L-shaped recovery, featuring a steep economic decline followed by a prolonged period of high unemployment and low economic output, highlighting how severe downturns can lead to lasting structural changes and an absence of swift recovery [19]. Some analyses suggest a K-shaped economy can be a 'pre-failure pattern' with resonances to the 1920s leading up to the 1929 crash [32].
