White workers viewed Black people not only as rate busters but also as political adversaries, since Black constituencies were generally aligned with the Republican Party—the party of Lincoln and emancipation, but also the party of big business—while white union members sided with the Democratic Party, seen as more sympathetic to labor and immigrants.
Looking back at this now, it parallels the current climate against immigrants. Particularly Latino ones but every non-white is a threat to jobs and livelihood for no good reason.
