My first reaction was to think "it's not just perceived"... but after a little introspecting, I couldn't help but notice how grim that statement actually is. It means that any mistreatment is fine - as long as the person can be distracted from it.
And thinking about that reminded me how every new tech since the internet/90th has been increasingly distracting. There is a reason we've started calling it the attention economy after all...
The way many people use the Internet now reminds me of an episode of Star Trek TNG ¹ where everyone is hooked on a game.

and it really should be a fundamental aspect of how companies are viewed.
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.
