Illegal immigration and guest workers visa use is of course the modern equivalent of slavery—and the characteristics associated with the Native born Americans in the areas in which these practices are prevalent appear to be much the same and De Tocqueville originally noticed:

A century had scarcely elapsed since the foundation of the colonies when the attention of the planters was struck by the extraordinary fact that the provinces which were comparatively destitute of slaves increased in population, in wealth, and in prosperity more rapidly than those which contained many of them. In the former, however, the inhabitants were obliged to cultivate the soil themselves or by hired laborers; in the latter they were furnished with hands for which they paid no wages. Yet though labor and expense were on the one side and ease with economy on the other, the former had the more advantageous system. This result seemed the more difficult to explain since the settlers, who all belonged to the same European race, had the same habits, the same civilization, the same laws, and their shades of difference were extremely slight.

…The influence of slavery extends still further: it affects the character of the master and imparts a peculiar tendency to his ideas and tastes. Upon both banks of the Ohio the character of the inhabitants is enterprising and energetic, but this vigor is very differently exercised in the two states. The white inhabitant of Ohio, obliged to subsist by his own exertions, regards temporal prosperity as the chief aim of his existence; and as the country which he occupies presents inexhaustible resources to his industry, and ever varying lures to his activity, his acquisitive ardor surpasses the ordinary limits of human cupidity: he is tormented by the desire of wealth, and he boldly enters upon every path that fortune opens to him; he becomes a sailor, a pioneer, an artisan, or a cultivator with the same indifference, and supports with equal constancy the fatigues and the dangers incidental to these various professions; the resources of his intelligence are astonishing, and his avidity in the pursuit of gain amounts to a species of heroism.

But the Kentuckian scorns not only labor but all the undertakings that labor promotes; as he lives in an idle independence, his tastes are those of an idle man; money has lost a portion of its value in his eyes; he covets wealth much less than pleasure and excitement; and the energy which his neighbor devotes to gain turns with him to a passionate love of field sports and military exercises; he delights in violent bodily exertion, he is familiar with the use of arms, and is accustomed from a very early age to expose his life in single combat. Thus slavery prevents the whites not only from becoming opulent, but even from desiring to become so.
