Ronald Reagan saved the auto industry from being destroyed by the Japanese. His accelerated depreciation allowed business to write off capital equipment at the same rate the Japs and Germans were, which is why they were building better cars than Detroit.
In 1980 the question on Wall Street was if by 1990 there would be three car companies operating in America or only two. Reagan fixed that. If your brains were gunpowder you couldn't blow your nose.
