If you are referring to the most recent economic recession (not the Great Depression), the industry hardest hit was the building material and supplies dealers industry.
The automotive industry was among the hardest hit during the Great Recession of 2008-2009, facing declining sales due to tightened credit and changing consumer preferences. The U.S. government intervened with bailouts to prevent major automakers from going bankrupt. Overall, this recession led to massive job losses and widespread economic hardships across multiple sectors.
