The economy grows through productivity. The effect of money on the economy is just an illusion. The U.S. government pumped trillions of dollars into the economy over the last couple of years and the economy grew at a rapid pace, but now with inflation kicking in we are seeing that those gains were not real. Real wages (wages after accounting for inflation) are now falling.
My question for you is, why do you think that money printing is necessary for economic growth? The world experienced tremendous economic growth before fiat money was invented.
They simply devalue the dollar, as was done when there was a gold standard.
