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.
The banks become parasitic when they become regulated, and capture the regulators. Unregulated banks are not parasitic; the host can reject them if they do not stay within useful bounds. Once the government begins protecting the banks, however, and granting them monopolies, they can and will destroy the Republic, just as Jefferson foretold:
“If the American people ever allow the banks to control the issuance of their currency, first by inflation and then by deflation, the banks and corporations that will grow up around them will deprive the people of all property until their children wake up homeless on the continent their fathers occupied … I sincerely believe the banking institutions having the issuing power of money are more dangerous to liberty than standing armies.”
