"The bank mania… is raising up a moneyed aristocracy in our country which has already set the government at defiance, and although forced at length to yield a little on this first essay of their strength, their principles are unyielded and unyielding. These have taken deep root in the hearts of that class from which our legislators are drawn … and thus those whom the Constitution had placed as guards to its portals, are sophisticated or suborned from their duties."

Thomas Jefferson's fears about the potential capture of government by a wealthy minority mirrored his experiences in Europe where, acting as the American ambassador to France before and during the French Revolution, he saw at first hand the effect of government under the control of the rich and the powerful, where hereditary monarchs ruled by divine right: by the will of God. In Jefferson's view the American constitution needed to ensure that the state was prevented from setting aside its revenues for a favoured few: because otherwise the difference between the actual aristocracies that governed Europe in their own interests and the "moneyed aristocracies" overseeing the United States would differ in no way meaningful at all.
Equating this version of democracy with capitalism is no great leap: if everyone is possessed of equal rights and opportunities then that some succeed and become wealthy and others fail and don’t is to welcomed. However, if the rich and powerful can suborn the government to protect their interests at the expense of everyone else, then this is not capitalism; and it risks being not democracy, too. That those who rig the markets in their favor then accuse those who protest of being anti-capitalists is no surprise, merely the behavior of tyrants everywhere. Capitalism requires that those who take risks and win should be rewarded, and that those who lose should be punished, not bailed out by a compliant state like a medieval monarch dispensing largesse by divine right.
