There's a book called Freedom's Forge that I'm a fan of, it makes the argument that the Auto Industry (And assembly lines, mechanization in general) were the single most important reason the Allies won WWII. In fact all the big auto manufacturers of the time retooled their assembly lines to build tanks and airplanes. It's conceivable that if we never mass produced cars, the US wouldn't have had the capability to win the war.
