Answer:
John C. Calhoun did not believe funding internal improvements would lead to the end of slavery. In fact, he thought quite the opposite.
According to John C. Calhoun:
• Funding internal improvements, such as roads and canals, would benefit the Southern economy and help spread slavery further into the Western territories.
• He adamantly opposed any limits on the expansion of slavery and saw internal improvements as a way to spread the "peculiar institution" into new regions.
• Calhoun believed slavery was a "positive good" and a fundamental part of the Southern way of life, not something that would eventually end.
• He argued that internal improvements funded by the federal government should disproportionately benefit the Southern states in order to compensate for the costs of maintaining the slave system.
• Calhoun saw any attempt to restrict the expansion of slavery as a threat to Southern interests and an unconstitutional intrusion on states' rights.
So no, based on Calhoun's well-established views, he certainly did not think funding internal improvements would lead to the end of slavery. In fact, he supported them as a means to spread and strengthen the slave economy in the South and West. Ending slavery was the farthest thing from his mind.
In summary, John C. Calhoun's position was that internal improvements should primarily benefit the Southern slave states in order to compensate for the burdens of the "peculiar institution." He certainly did not see them as a potential path to ending slavery, which he adamantly defended.
