We read at aeon.com, that "Between 1776 and the present, the United States seized some 1.5 billion acres from North America’s native peoples..." This so signifies that by the forced removal of American Indians – we find that those American Indians that were still alive from this forced eviction, ended up essentially being relegated to those faraway and uninhabited western lands of little or no worth, which thereby correspondingly meant that those that thus obtained that land so left behind by that forced removal, would thereby possess some of the most valuable fertile land that so existed at that time.
Not too surprisingly, the land distribution of those lands seized from American Indians of the South was always going to go to those that were well positioned to receive those lands, who would subsequently then readily use slave labor as the means to get the best production and wealth from those same lands. It has to be remembered, in a day and age, in which land was the primary form of wealth, those that own good land that could be utilized for crops, or cotton, or any other item of value, had placed themselves in the enviable position to make not only a considerable amount of money, upon the backs of those so enslaved, but also to utilize that wealth to sustain and to increase the plantation power within those Southern States, so that their desires would thus be continually fulfilled.
Additionally, white people of all social classes, appreciated the seizure of American Indian land, because they too were able to receive either some of that land for their own benefit, or if not, were better able to find good work to enhance their status, position, and security; of which, it should be noted, back in those days before the Civil War, the per capita income of those that were free men in the South, was meaningfully higher than those of the North.
So then, not only was wealth created upon the backs of enslaved African-Americans that were forced to work as laborers upon those plantations, but the very land that Southern plantations were built upon, was quite frequently, lands that had originally been in the hands of American Indians, that was thus seized from those American Indians, essentially at gunpoint, or through treaties that were not honored in either word or in spirit. In other words, when we think about the evils of slavery, we need to also take into account, that the American Indian, though not enslaved, was forcefully removed from what had once been theirs, and of which, many an American Indian, did not even survive the "trail of tears" when so forcefully removed from their land.
Perhaps, it could be said that the lands so taken from the American Indian, ended up being a good thing, because those that instigated that action, help to create the basis for what has become the most powerful and richest nation in the world. Perhaps though, it could be added that America has blood on its hands, for its dishonesty, trickery, and unfairness, so utliized against minorities of all types, which has created a karmic price to pay, that has not yet been paid, and hence is seriously past due.
