Diversity in the service of freedom might be a very good thing. Diversity in the service of slavery might be a very bad thing.

In the decade from the Declaration to the Constitution every state north of the Mason Dixon line, and north of the Ohio River, either abolished slavery or adopted measures leading to abolition. But in 1793 the cotton gin was invented, shortly after the power loom in England. This was the onset of the industrial revolution. Almost overnight, a new industry or rather a series of new industries, proliferating worldwide, was born. It began with the growing of cotton but was followed by its manufacture into a wide variety of products, especially cotton cloth and cotton clothing. Suddenly, slave labor became vastly more profitable. In the decade before the Civil War, the value of slaves doubled. Once again, greed overwhelmed all other motives. From being regarded as a temporary evil, as it was at the founding, slavery came to be regarded as a positive—and permanent—good.

Now there’s document on a subject of states' rights and states' sovereignty which is very seldom cited but which is absolutely fundamental to understanding the status of sovereignty under the Constitution: the letter that George Washington wrote transmitting the new Constitution to the Congress on September 17, 1787. And among the ironies of this letter is the fact that John C. Calhoun in his Discourse on the Constitution and Government of the United States, the sequel to his Disquisition on Government, cites the words that Washington used to support his position that this was a federal government, and that “federal” meant one in which the constituent parts retains complete sovereignty. And he refers to the fact that Washington refers to “the federal government of these States.”
