Our countries' must have gone through inflation as a nation at least once or more since its history.
Inflation is a constant process that occurs in all countries of the world without exception. The only difference is that the inflation rate differs depending on the economic state of the country. In developed countries it is less, in developing countries it is more.
As a refresher, inflation happens when the prices of goods and services rise and people can no longer afford those items because the country's money almost becomes useless.
It is not the price of goods and services that increases, but the purchasing power of money that decreases. That is, the same unit of money can buy fewer goods and services. This would not happen if the amount of money in circulation were constant, but new money is printed almost every day, therefore, its value decreases.
But is inflation needed? Why can't we just keep the currency at the same value? And why does it only happen to money?
Inflation is not a removable part of the modern world economy. Because only money has no limit to its creation.
For example, the same wouldn't happen if we used gold as a currency instead.
Gold was used as a currency up to a certain point, but this prevented the world economy from developing more intensively (due to lending with unsecured money).
Is inflation a ploy that the government uses so people don't get rich off of savings?
Governments have no alternatives other than the existing economic model.
There is such a thing as an "inflation tax", so in a sense, governments benefit from this situation (by making citizens' money cheaper and printing money out of thin air as much as they want).
