Inflation is just redistribution of wealth. The above article accounted for 2 scenarios. When you get an amount of raise equal to inflation and when you don't get a raise and you become poorer. However for every case of someone not getting a raise equal to inflation there is someone who gets more than that.

My wife and I got 8% raises this year respectively which I assume is above inflation rates. We also got 10% raises the year before.

Inflation is just a tool to redistribute wealth and that is all there is to it. People who start to swallow the increase in prices are the ones who get shafted on the deal and the ones who raised the prices in the first place reap the benefits. Sure you need to account for increases is price but as long as you're on the better end of the inflation stick you've got nothing to worry about other than using larger numbers in your budget.
