Inflation sucks, a bottle of Coke is 4 times more expensive than it was just a couple years ago but salaries haven't increased anything near that
This would only make sense if you kept X amount of money over Y period of time (hoarding the currency).
I suspect it's either the one selling the bottle of coke (the price has in fact gone up and they're profiting more) or the one paying you the salary ripping you off (they're actually paying you less than before), not problem of the currency you're using.
The exactly same thing can easily happen with deflation: your salary will decrease, but price of the bottle of coke will remain the same.
