What is inflation? Types of inflation? Why is the state fighting high inflation?

Inflation is the process of raising the general level of prices in the country, leading eventually to a decrease in the purchasing power of money.
No more than 3 – 5% per year (creeping inflation)
About 10 – 50% per year (galloping inflation)
Over 50% per month for 3 to 4 months (hyperinflation)
The struggle is going on because the income and savings of families, the profits of firms, the state budget are devalued, and under conditions of sharp inflation, production decreases and unemployment grows, the standard of living of the majority of the population is declining, and poverty is growing rapidly.
