JFK, like Lincoln, wanted to end private banking financing the nation. The true global oligarchs are at the top of the food chain, the international banking powers.
Ironically, the 1964 Kennedy Half Dollar was 99% silver (or 100%).
I have heard that Kennedy wanted to put the US back on the Gold Standard... I imagine he would have allowed the opening of Gold mines that had been closed during FDR. (Some of which were not that economical to re-open because of flooding).
