why did jackson believed the bank was unconstitutional
President Andrew Jackson opposed the Second Bank of the United  States because he believed that it held too much power without  accountability and undermined the rights of s â¦ tates. Furthermore, it  used that power to benefit the old Eastern establishment and  shortchanged the farmers on the frontier.he Bank of the US was run by the rich people in the Eastern US. It gave preferential treatment to business interests in the East and was not of service to Jackson's people on â¦ the Western frontier.
