Which union secured their members a 10% wage increase in the past year?
The poor are the most affected by inflation. Just because their spending pattern doesn’t shift doesn’t meant they aren’t affected. The shift in spending patterns is a way to avoid the effects of inflation. A person whose income cannot be diverted is the most effected.
It’s like a plane is crashing and one person ejects while the other person doesn’t. Yes getting ejected from a plane’s cockpit is a high energy event. But crashing in the plane is an even higher-energy event.
The people who you are saying are “most affected” by inflation are experiencing those effects in the activation of anti-inflation mechanisms in their life. Those anti-inflation mechanisms while they do represent an effect are not as big as the effects felt by those without access to those mechanisms.
