That's the dirty nuance of it. One can certainly have stress or frustration based on truly perceived unfairness. Take the case of someone who gets more test time because of a disability and the ADA. Those who don't know the why, may find it unfair. And there may be people that perceive it as unfair despite it being overall accepted as such. ---- That said your observation is also entirely true in it's own right. You can even distract from the real problem by focusing one's attention on a different unfairness, even if that unfairness impacts them less in the short and/or long term.
