The growth of the industrial base of this nation during the period up to the Civil can be attributed to tariffs. It was the sole source of income for the federal government and remained the major source until the 1940's. The founding fathers grasp the simple concept that it was the only way that the nation could obtain economic independence. That is to be self sustaining and a exporter of finished good rather than an exporter of raw resources and and importer of finished goods.
This is what has transpired during the last fifty years as corporations have gained control of Congress and have been rewarded with policies that have decimated our industrial base. One of the key components in this war against the working class has been the destruction of unions which left the working class with little or no support in Congress to protect their interest. The sad fact of the matter is that the workers have brought this on their own-selves. Throughout the South, for example, the working class bought into the so-called Right-to-Work laws that eventually destroyed the textile industry resulting the massive loss of jobs. Perhaps the workers will wakeup before the nation becomes little more than a massive service industry of low paying jobs with no future and as desperate as the foreign workers that are being exploited.
