Abner E. Woodruff, Evolution of American Agriculture (c/1919)
“ As slavery had thrived on tobacco in the early days of the colonial period, it now thrived on cotton in the early days of the national existence. Undoubtedly slavery would have died a natural death but for this development of the cotton growing industry. And yet, slavery stifled the South by preventing immigration into that region. Free labor cannot exist comfortably alongside the slave, because it is called upon to help bear the stigma that is cast upon labor by the fact of slavery. ”
