It's caused by Modern Monetary Theory. MMT is the insane idea that if the government needs money all they need to do is just print it. It doesn't matter how much it costs just print the money.
Even some of the "economists" who are promoting this theory worry about inflation but they thing that all they need to do to stop inflation is to have Congress pass a law.
This theory is being promoted by the International Monetary Fund and the World Economic Forum and it's being pushed globally not just the US. It's a critical part of the great reset.
