if the money is printed too much, then the residents will automatically hold a lot of money. That way, our buying ability is high and the items we buy will be reduced. The amount of money in circulation will cause inflation. That is an increase in the price of goods and a decline in the value of a currency.
The amount of money in circulation will cause the price to adjust upwards, so that money becomes less valuable and more worthless because there are too many.
Therefore, the government prints money according to needs. Not too much and not too little, to avoid inflation.
