Why were southerners upset by the level of traffic in 1828?

Southerners were upset by the level of traffic in 1828 primarily due to the increased movement of goods and people, which they perceived as a threat to their agrarian lifestyle and economic interests. The rise of northern industrialization and urbanization led to concerns that the South's reliance on agriculture and slavery would be undermined. Additionally, the growing influence of northern interests in national politics fueled fears that policies would favor industrial development over southern agricultural needs, exacerbating regional tensions. This discontent was part of a broader pattern of southern anxiety about their position in the evolving American economy and society.
