The economic impact of money printing

Printing a lot of money at will => short-term economic improvement (the central bank gives banks, banks give manufacturers, manufacturers buy things for employees and employees, very good!), but consumption has a consumption limit, too much consumption will cause inflation, And now inflation is out of control.

MMT (modern monetary theory) supports money printing. People know that inflation may be caused, but they only want the economy to be good for a short period of time, support money printing, and finally cause inflation.(The US Federal Reserve's increase in deposit rates is not actually to control inflation, but to recycle banknotes to the central bank.)
