Answer:
Governmental developments such as the United States Bank, which acted as the "main financial agent of the country", and innovations that helped to develop the economy (railways, canals, bridges, etc.) improved the nation's economic integration together.
Though those advances improved, they often came with negative effects. Many resented the 2nd National Bank (since they "always deposited much more cash in their safes than the space", which caused the value of paper money to remain inconsistent), the 1819 Crisis (where many reported depression and the unemployment) occurred, and issues such as the Missouri Controversy all hampered the actions.
