Most importantly, Andrew Jackson broke the power of the duopoly of the early years of the Republic, where power was shared between the Tidewater aristocracy and the mercantile interests of the Northeast. The farmers who were settling the Appalachians, the Ohio Valley, and the Mid-South were poorly represented by the two elites, as was the growing working class in the East Coast cities. While Jackson was as wealthy as any of his predecessors, except Washington, he was a common man, the son of recently arrived Scots-Irish immigrants to the Carolina Piedmont. He grew up in poverty.
He was a slaveholder, but so were four of the first six Presidents. He waged war against the Indians and expelled them from their ancestral homelands, but so did Lincoln and Grant. Washington and Jefferson were also advocates of aggressive settlement of whites throughout the continent.
For the PC sins of being a slaveholder and supporting dispossession of the Indian nations, every President or major important official prior to 1900 should be expunged from the currency. We would have to destroy Washington and Jefferson's monuments, and maybe those to Theodore Roosevelt, who believed in Nordic supremacy as well and who waged war against the Muslim terrorists in the Philippines.
They’ll eventually get around to expunging George Washington because he was a slave owner.
