Final answer:
Southerners hated the Tariff of Abominations due to its favorable impact on the North, potential threat to slavery, and costly impact on southern importers, but not because it would stall their thriving economy.
Step-by-step explanation:
Southerners opposed the so-called Tariff of Abominations (1828) for several reasons, but one concern they did not have is that the tariff would stall their thriving economy. Instead, their main concerns included the belief that the tariff favored the North over the South, due to the North's expanding manufacturing base. They also feared that the tariff's demonstration of federal power could lead to further action against southern interests, particularly regarding slavery. The South had little manufacturing and relied on purchasing manufactured goods, which were now more expensive due to the tariff. Furthermore, they were concerned that tariff revenues were funding government projects that benefitted only the North. Lastly, the Tariff of 1828 heightened fears about the potential for a federal intervention in slavery, as it showcased the power of a northern majority in Congress that could act against southern states' interests.
