Also, the government decides to print out more money too. Bank's interest rate also changed to lower compare to before in some countries. People put all their savings to gold or stock as they consider it was a safe channel to hide over this time. Definitely something in the recipe for disaster. My prediction is the real estate crash will trigger the start.
QE and low interest are always side by side and are usually used as a weapon to re-setup the economy because it is overvalued because the money is printed dozens of times compared to the existing underlying project. The way of resetting is for capitalists to discard overvalued paper by allowing the stock market to crash. Because the losers are small investors, while large investors like Berkshire Hathway have left first and are holding cash.
When the economy, social and politics of the global world are disrupted by corona for several months and even the effects could be several years in the future, the FED will print money so that capitalists and oligarchs can buy everything in the world. And the wars that are used to legitimize the use of weapons are propaganda wars, media wars and wars on social media and biotechnology wars.
So printing money, aka QE, has always been the savior of the US from the habit of printing excessive money because of overconfidence, the majority of dollars circulating abroad, not domestically, and dollars circulating abroad are mostly controlled by Wall Street. Besides that, the procamp language likes the US because the US created the system.
