In 2008+ when they “printed money” via “Quantitative Easing”, they would buy bonds off the market. This puts printed money in the hands of bond holders. Presumably bond holders are very rich. Presumably very rich people already have a good enough car and already frequent restaurants. Now if the Fed printed money and put it in the hands of the middle class, not just the hands of the upper class, I’d bet you new cars would be bought and restaurants would be dined.
