The Louisiana Purchase was financed with money borrowed from European bankers, I think. I don’t know what Jackson would have done, but his quarrel, as I understand it, was not with borrowing money, a power expressly conferred in the Constitution; it was with chartering banks.
No parasitic British and Dutch bankers, no Louisiana Purchase.
As for Andrew Jackson...you're right, he had no aversion to bankers, but rather to the chartering of a National Bank. Still not sure why you cited him as being "against the parasitic banking entities" since he removed all Federal monies in the National Bank and deposited them in "parasitic" banks.
