Final answer:
The vision of free labor where freed Blacks would labor more productively than they had as slaves was a belief held by proponents of the free labor ideology in the North. They argued that a free labor system would lead to economic growth and provide opportunities for social mobility.
Step-by-step explanation:
The vision of free labor where freed Blacks would labor more productively than they had as slaves was a belief held by proponents of the free labor ideology in the North. They believed that slavery robbed both slave and free labor of its dignity, and that without the incentive and freedom to choose their employers, workers became less productive. They argued that a free labor system, where workers could choose their occupations and profit from their labor, would lead to economic growth and provide opportunities for social mobility.
This vision of free labor was seen as a contrast to the slave-based economy in the South, where poor whites were also believed to lack opportunities to improve their social and economic standing. Northerners sought to create a free labor system in the South, but were hindered by the political dominance of the slave-owning South.
Overall, the vision of free labor emphasized the importance of personal freedom, opportunity, and economic independence.
