Cumulative inflation since 2018 is only 22%.
So if the price of a McChicken had kept up with inflation we'd be at 1.22
But inflation isn't a flat percent just like IQ isn't. And almost everytime we experience inflation, it's hits the essentials the hardest. Food, housing, medical care, all that shit goes up at much higher rates than things people don't really need.
Because if they raise the price too much, people just stop buying them
If all the landlords decide to raise rent due to inflation, everyone still has to pay.
When the handful of grocery chain decide to increase costs, it's still cheaper than ordering out, and everyone has to eat
Inflation has always been an excuse for everyone to simultaneously raise their prices without it being collusion.
