Answer:
There are several reasons why the recession that took place between 1973 and 1975 affected not just the United States, but also the rest of the world. In the case of the United States, one of the first causes was the negative effect that the whole Nixon scandal had, and which caused a fall of the Bretton Woods system. Also, a rise in competition with other industrialized countries, like Japan, Great Britain, and France, made American-made products less competitive, which drove sales down. Finally, the stock market crash of 1973-74, all became reasons that drove forward this recession, the biggest and most dangerous after the Great Depression, and only overcome by the 2008-09 recession. But probably what nailed the recession, which was caused by hiperinflation and unemployment, was the 1973 Oil Crisis that was generated through the steep increase of oil prices by producing countries, like the Arab nations, after an embargo they had set on the product a year before. This increase in prices affected many countries, but it targeted mostly countries who were pro-Israel.
