How did industrial technology impact sectionalism

The Industrial Revolution era helped spread sectionalism throughout the US in the early 1800´s.  

While the north was industrialized, the south was based on agriculture and textile inventions rather than machines, which meant developing unique and separate cultures.  

Furthermore, given their production system only the south needed slavery. Congress favoring the north on this issue aroused the sectionalism dispute.

the main objectives of the progressive movement were eliminating problems caused by industrialization, urbanization, immigration, and political corruption.
