Seems pretty clear the anti market forces were aligned on behalf of slavery.
What is capitalism’s view toward slavery? It seems like a crazy question, but not so much actually, not in these times. So let us begin with the opening line of the first chapter of George Fitzhugh’s Sociology for the South, first published in 1854.
Political economy is the science of free society. Its theory and its history alike establish this position. Its fundamental maxim Laissez-faire and "Pas trop gouverner," are at war with all kinds of slavery, for they in fact assert that individuals and peoples prosper most when governed least.
Fizhugh’s point was to inveigh against economic freedom and in defense of slavery. His radical tract sought to make out an elaborate ideological case for slave labor and indeed all aspects of social ordering. Such a system, he announced, would resolve the posited state of perpetual conflict between labor and the owners of capital by supplanting it with the paternalistic hierarchy of slavery — a model he advocated not only for the plantations of the South but also for adaptation to the factories of the Northeast.
