No country really does but one of the reasons why a country goes into a crazy inflation rate is because of the corrupt leadership of a country and as well as sanctions.
That is one thing but actually, inflation as a concept alone is very complex and if it indeed affects a country there would be basically a domino effect that would happen in the country.
Inflation means less purchasing power and higher prices. Because of this workers would most likely rally and demand higher salaries. Higher salaries would mean more demand and thus income disparity will just get worse and worse. It will be basically a cycle of one thing increasing then the other would follow and so on and so forth.
Inflation would take time to be solved and will not be solved by just one policy implemented that is why it is so hard to take control of it.
IMHO, most countries do have the same problem whether they're a first world country or a third world or a developing nation. The governments can't just increase the salaries as soon as the people want it to be. But they have ways of increasing it and how to deal with it through yearly increase or whatever they are dictating to the private companies for them to help an individual cope up with the rising prices that's seen not gonna stop anytime soon.
