Hi. Recovered crackpot here. You're stuck on a few ideas, routinely propagated by people overwhelmed by the complexity of the interface between global economics and politics, and made attractive by their apparent simplicity, that I have previously considered, and already thought myself out of.

The Fed:

The Fed is a pseudo-governmental organization, like the Postal Service or the Federal National Mortgage Association ("Fannie Mae"). It has a variety of member banks, but they do not control the Fed. They disproportionately benefit from it, but they are not directly in charge. The Fed is their cartel enforcer; none of them could trust the others to run it fairly. It has to be independent of the banks. And it has to be independent of politics. It is its own selfish little entity, with a [public] dual mandate of ensuring full employment and low [demand-pull] inflation. It can never truly succeed at both, but it can certainly fail at both.

Your concerns seem to be focused on fiat money. The actual danger, adequately managed by the Fed, is fractional reserve banking. When left un-cartelized, fractional reserve wreaks havoc on the money supply, and asymmetric settlements eventually cause banks that are too profligate with their lending to fail, and those not profligate enough to be outcompeted. The Fed standardized the reserve fraction, so that the member banks could lend money that did not previously exist and charge interest on it, making debt into the largest part of the monetary basis, and real savings and production into a minority contributor.

The secondary private mandate of the Fed is to manage the reserve ratio and settlement rates such that no individual bank can get greedy, go rogue, and destroy the whole system that otherwise makes a whole lot of people a whole lot of money for doing very little actual work.

Don't get me wrong. The Federal Reserve System is a great way for the rich to stay rich and keep the poor from rising, and there is no social justice in the system it manages. But it is a perfectly reasonable technical solution for greedy bankers destroying the whole economy via exuberant overreach--which they would otherwise do (more frequently) if left unchecked. If you assume greedy bankers will always exist, the Fed is the lesser evil. They actually are stealing some of your hard work and giving it away to rich people, but probably nowhere near as much of it as you think, and you do benefit from their work more than you may expect.

There is nothing inherently bad about fiat money. Money in its purest form is just a mutually agreeable unit of accounting. As long as there exists some fair process for matching the size of the money supply to the current level of economic activity, fiat money works fine for everyone. Counterfeiting is what spoils it. And lending additional money into existence based on fractional reserves of currency is counterfeiting-by-the-law. It's a similiar unethical con to "naked short-selling".

JFK:

The exact reason why JF Kennedy was assassinated is now indeterminate. There isn't enough forensically-reliable evidence remaining to support any postulated conspiracy, or ascribe motive to any of their principals. Personally, I favor the hypothesis that he was killed by racists to delay or reverse civil rights gains for minorities. The red-sealed direct-issue US notes, to replace green-sealed Fed notes, are a long-shot motive hypothesis, at best.

We don't know why JFK was killed. It is no longer possible to answer those questions or verify those claims. Thinking about JFK is probably going to be a time-wasting distraction from questions you can actually answer via independent analysis. There are just so many holes in the JFK story now, you can easily project onto it, which is only going to tell you more about yourself than anything about the real world. So drop it, if you can. There are plenty of stories from this century that you can look into. Why not try to prove that SCotUS justice Scalia was murdered?

Spending:

The spending free-for-all is... wait... what spending free-for-all? Rich folks are stockpiling cash, loaning it, and investing it, not spending it. There's no [demand-pull] inflation, because the money the Fed (and its member banks) is creating is never actually making it to the pockets of consumers.
