You left out a very important one: high energy prices, which affect everything. If gasoline and electricity prices go up, you not only pay more to fill up the tank and for the electricity in your house, you will also pay more for groceries, for example.
In fact, the inflation we have been experiencing for a couple of years now is mainly due to energy prices and massive post-covid printing. Then it was exacerbated by the Ukrainian war, but it started earlier.
That's true because with the increasing price of petrol every other materials also get expensive so if the price of petrol and gasoline are under control then inflation will also be able to Control.
Inflation does not effect only poor but its also a big threat for wealthy people and everything is of higher cost instead of vast amount of resources present in our country. May be the country's leader do not have any idea about the uses of these resources or may be they are scarcity of these resources but what I know is that here is abundant of gas, petroleum and water resources so they should worked on it to provide for each and every individual of a country.
