Final answer:
The American System instituted protective tariffs, a national bank, and internal improvements, fostering U.S. economic growth and industrialization. Opposition arose due to regional disparities and concerns over federal power.
Step-by-step explanation:
The American System was a plan to strengthen and unify the nation's economy in the early 19th century through protective tariffs, a national bank, and internal improvements such as transportation infrastructure. This system transformed the U.S. economy by fostering industrial growth in the north and contributing to the development of a national market. The protective tariffs aided nascent American industries by reducing foreign competition, which in turn increased domestic manufacturing. The national bank aimed to stabilize currency and credit, whereas internal improvements allowed for the faster movement of goods and resources across the country.
However, the American System was met with opposition from various sections of society. Some people disliked the system because they felt it favored certain regions over others, namely that it benefited the industrial North at the expense of the agricultural South. The increased tariffs angered Southern states that relied on imported goods and the export of raw materials. Additionally, there were political concerns about the strengthened role of the federal government, which some argued infringed on states’ rights.
