The Northern states were in favor of Hamilton's protective tariff primarily because:
- The tariff allowed manufacturers in the North to charge higher prices for their products.
The protective tariff imposed duties on imported goods, making them more expensive compared to domestically produced goods. This benefited Northern manufacturers, who produced goods that would now be more competitively priced relative to imported products. As a result, Northern industries could thrive without the threat of being undercut by cheaper foreign goods, which ultimately supported economic growth in the region.
Another reason, although not specifically listed in your options, is that the Northern economy was more industrialized compared to the agrarian South. The protection of emerging American industries was crucial for the North's economic interests.
