Hitherto, in the United States, our cheap and fertile lands have acted as an important safety-valve for the enterprise and discontent of our non-capitalist population. Every hired workman knows that if he chooses to use economy and industry in his calling, he may without great or insurmountable difficulty establish himself in independence on the public lands; and, in fact, a large proportion of our most energetic and intelligent mechanics do constantly seek these lands, where with patient toil they master nature and adverse circumstances, often make fortunate and honorable careers, and at the worst leave their children in an improved condition of life. I do not doubt that the eagerness of some of our wisest public men for the acquisition of new territory has arisen from their conviction that this opening for the independence of laboring men was essential to the security of our future as a free and peaceful state. For, though not one in a hundred, or even one in a thousand of our poorer and so-called laboring class may choose to actually achieve independence by taking up and tilling a portion of the public lands, it is plain that the knowledge that any one may do so makes those who do not more contented with their lot, which they thus feel to be one of choice and not of compulsion. Any circumstance, as the exhaustion of these lands, which should materially impair this opportunity for independence, would be, I believe, a serious calamity to our country; and the spirit of the Trades-Unions and International Societies appears to me peculiarly mischievous and hateful, because they seek to eliminate from the thoughts of their adherents the hope or expectation of independence. The member of a Trades-Union is taught to regard himself, and to act toward society, as a hireling for life; and these societies are united, not as men seeking a way to exchange dependence for independence, but as hirelings, determined to remain such, and only demanding better conditions of their masters. If it were possible to infuse with this spirit all or the greater part of the non-capitalist class in the United States, this would, I believe, be one of the gravest calamities which could befall us as a nation; for it would degrade the mass of our voters, and make free government here very difficult, if it did not entirely change the form of our government, and expose us to lasting disorders and attacks upon property. We see already that in whatever part of our country the Trades-Union leaders have succeeded in imposing themselves upon mining or manufacturing operatives, the results are the corruption of our politics, a lowering of the standard of intelligence and independence among the laborers, and an unreasoning and unreasonable discontent, which, in its extreme development, despises right, and seeks only changes degrading to its own class, at the cost of injury and loss to the general public.
