"Sue didn't work as hard as me"
"Bobby isn't the idea man"
"I don't owe Claire anything, she took 2 days off sick last year"
"Carl's only a contractor, I can pay him 2 months late"
"Jay only contributed a tiny amount at the beginning, now he does nothing, it's time to cut him loose"
"Sally just isn't a cultural fit any more"
Or simply "I worked so much harder/am brighter/deserve it more than most people, I'm allowed to be a bit selfish".
It's the same thing as power being corrupting.
