[S]lavery was neither a backward nor a dying system in the 1850s. It was aggressive, dynamic, and mobile, and by pandering to the racial prejudices o… - Allen C. Guelzo

[F]or all the economic destruction levied on the South by the war, the people who ran the economic show before the war were still running it afterwards. Former slaveholders were thus free to use cotton profits to maintain a version of the plantation system and force the freedpeople into peonage; peonage, in turn, gave white Democrats the power to control black voting...

Today’s despisers of free speech have their roots in a different ideology from the tribal sort that was used to justify slaveholding and Puritanism.

Rather than joining in solidarity with the working classes of other nations, European workers rallied in dismaying numbers to their national flags, exhausted themselves in a four-year killing spree that beggared all previous descriptions of war, and then succumbed to waves of populist fascism. The only revolution that Marxists could tease out of the charnel house of the Great War was a coup d’état in the most backward and least industrially developed empire of Europe and, even then, only by the substitution of what Vladimir Lenin called a “vanguard” of Marxist elites rather than a spontaneous uprising of the workers.

To Lincoln, slavery undercut the free labor outlook on the world because it denied advancement and self-improvement. For Lincoln, the great attraction of any economic regime was the degree to which it permitted accumulation and self-promotion. He once described the ideal system as being one where the penniless beginner starts out working for somebody else, accumulates capital on his own by dint of savings, goes into business for himself, and then eventually becomes so successful that he hires others, who in turn continue the cycle. And he spoke of that as being the order of things in a society of equals. For him, the very notion of equality is a matter of equality of openness, aspiration, and opportunity.
