When the mainstream media covers the Federal Reserve, it is almost exclusively lies and propaganda. There is more misinformation on money and the Federal Reserve than any other subject. The Federal Reserve steals via inflation, and the proceeds go to banksters, politicians, and insiders.
There is a very simple argument against the Federal Reserve. “Inflation is theft!” Inflation steals from everyone. Insiders get the newly-printed money, giving them a huge economic advantage over everyone else.
The only way I can get money is by working. For banksters and politicians, they get to print new money and spend it on whatever they want.
The Federal Reserve is a price-fixing cartel. The Federal Reserve fixes interest rates. Interest rates are the price of money. Everyone agrees that it would be evil for the government to set the price of oil or most goods. The Federal Reserve is somehow exempt from normal economic analysis of monopolies.
Normally, the Federal Reserve keeps interest rates artificially low, compared to inflation. This sends a false economic signal to investors. With high inflation and low interest rates, it seems profitable to borrow and buy houses, stock, or whatever. This naturally leads to bubbles, booms, and busts.
A mainstream economist is actually a professional liar. Most economists say that the Federal Reserve is desirable. Most economists say that booms and busts are an economic law of nature. They actually are caused by a corrupt monetary system.
In the USA, the #1 employer of economists is the Federal Reserve. For the top economic journals, most of the referees worked for the Federal Reserve at one point in their career. Peer review becomes censorship, when most of the academic leaders in a field have false beliefs. If an economics PhD student sharply criticized the Federal Reserve, he would essentially be calling out all his peers as frauds. His papers would not be published, he would not get any grant money, and his career would be a failure.
If you want two simple arguments against the Federal Reserve, all you need is “Inflation is theft!” and “The Federal Reserve is a price-fixing cartel!” The Compound Interest Paradox is a more subtle argument against the Federal Reserve.
