Inflation is inherent in every economy.
Maybe you're thinking of hyperinflation that happend in Europe during the great depression when money became cheaper to burn than fire wood.
according to sources, the inflation starting date in the U.S. is roughly 1770
Current year's inflation - last year's inflation / last year's inflation * 100 e.g ((B-A)/A)*100
When inflation is volatile from year to year
This year's rate of inflation is 10% or [(121 - 110)/110] x 100.
A good description of "inflation" is an increase in prices and a fall in the value of money. Inflation is usually represented as a percentage increase for one month over the same month the previous year. Double-digit inflation is when this percentage is greater than 10%. If inflation rises even more than 100% (i.e. prices are twice s high as last year) it is usually called "hyper-inflation".

Inflation refers to the rate of increase of goods and services in a country Let us say the inflation rate of your country is 10% then whatever was worth $100 last year is worth $110 this year. This is the effect of inflation.
This year's rate of inflation is 10% or [(121 - 110)/110] x 100.
Inflation was the same thing back then as it is now. Inflation rates were and are different in different countries, so the amount of inflation in each country is always different, depending on the solidity of the local currency. In Britain the inflation rate in 1900 was 4.5%. In the USA it was 16.9% but then fell to -2.4 the next year. Inflation rates in the US changed greatly from year to year and were often double-digit (but sometimes that was double-digit deflation)
2016s rate was 4.85%, and the inflation rate was 2.5%
It's the difference between the yield on 10 year treasury bills and 10 year Inflation Protected T bills. The difference between the two implies what the market expects inflation to average over the 10 year period. When there's a big difference, inflation fears are high.

From the worker's perspective, raises are judged good or bad in reference to inflation. Its really a question of buying power more than the actual amount of money. Think of this example... If inflation is running 2% per year and you get a 2% raise, you break even. Your salary buys the same stuff at the start the year and the end of the year. If inflation is 2% and you got a 4% raise, you're now making more money than before. You have more buying power relative to the economy as a whole. So as a worker, your goal is to be able to buy more each time you get a raise. So if inflation is low, you can accept a lower raise and still increase buying power as long as the raise is higher than inflation. So when infaltion is low, a low raise (that's still bigger than the rate of inflation) just as effective as a large raise when inflation is high.
It may change, yes.
