Being able to ask such a question shows that the landlord still has some research, and the friends above also have some truth. Let me make some explanations about this problem. Everyone knows that 1 gold is expensive because it is scarce. Gold reserves are limited and mining is limited, so it is impossible to increase them at will. Gold is fixed so much, that's the price during the gold standard period. Paper money is directly linked to gold, so the number of paper money is relatively fixed, so the value of paper money is fixed, so inflation will not occur. Later, paper money was no longer linked to gold. As long as one more currency is issued, it will depreciate, and currency depreciation will cause inflation. 3 Inflation Whether it is the gold standard or the silver standard, as long as the currency in circulation (whether it is gold, silver, paper money or anything else) is guaranteed, as long as its quantity is relatively constant and its value can be relatively fixed, inflation will never occur. To sum up, the gold content is limited and does not depend on people's wishes. And paper money can be issued indefinitely, as much as you want. Gold will not depreciate, but paper money will. Once the currency depreciates, there will be inflation. Because gold is limited, its value is constant.
