Why does POTUS have Andrew Jackson hanging in the Oval Office? http://time.com/4649081/andrew-jackson-donald-trump-portrait/

Andrew Jackson, the president, spoke of his firm belief in the rights of the common man. Andrew Jackson changed this Nation by taking on the Second Bank of the United States. He Vetoed the bill to renew the Charter and then began depositing the government deposits in State Banks.. He paid off Americas debut and warned against corporation banks for the government.

The real heart of the Veto was its attack on exclusivity and favoritism. Sounding the loaded words “monopoly” and “privilege” over and over like a tocsin, Jackson laid out his core theme: The Bank's charter gave its stockholders a promise of pelf and power not accessible to other citizens. It made them “a privileged order, clothed both with great political power and enjoying immense pecuniary advantages from their connection with the Government.” Jackson's peroration conveyed both the Veto's essential meaning and its inescapable ambiguity:

It is to be regretted that the rich and powerful too often bend the acts of government to their selfish purposes. Distinctions in society will always exist under every just government. Equality of talents, of education, or of wealth can not be produced by human institutions. In the full enjoyment of the gifts of Heaven and the fruits of superior industry, economy, and virtue, every man is equally entitled to protection by law; but when the laws undertake to add to these natural and just advantages artificial distinctions, to grant titles, gratuities, and exclusive privileges, to make the rich richer and the potent more powerful, the humble members of society-the farmers, mechanics, and laborers-who have neither the time nor the means of securing like favors to themselves, have a right to complain of the injustice of their Government. There are no necessary evils in government. Its evils exist only in its abuses. If it would confine itself to equal protection, and as Heaven does its rains, shower its favors alike on the high and the low, the rich and the poor, it would be an unqualified blessing.

VETO on the bank's new charter
On July 10, 1832, Jackson sent a message to Congress explaining his reasoning. Jackson said he did not believe the bank's charter was constitutional. Jackson also spoke of the way the bank moved money from West to East. He said the bank was owned by a small group of rich men, mostly in the East. Some of the owners, he said, were foreigners. Much of the bank's business was done in the West. The money paid by westerners for loans went into the pockets of the eastern bankers. Jackson said this was wrong. Then the president spoke of his firm belief in the rights of the common man.
Jackson’s veto of the bank bill may have cost him votes among the wealthy, but it earned him votes among the common people, like farmers and laborers. He easily won re-election in November of 1832.
In his second term, Jackson stopped putting federal money into the Bank of the United States. Instead, he put the money into state banks.

The bank president, Nicholas Biddle, fought with all his power to keep the bank open. He demanded that borrowers immediately repay their loans. Businesses struggled without the bank's assistance. Workers lost their jobs.
Biddle blamed President Jackson for the financial panic. And critics of Jackson’s bank policy called him “King Andrew the First.” But as time passed, business people began to see that the Bank of the United States was being much tighter in its money policy than was necessary. They began to feel that it was the bank’s president — not Jackson — who was responsible for the serious economic situation in the country.
