No reason? You even stated the reason "for promotion". It's OK if you are not aiming for promotions but don't judge others when they do.

Found the treadmill runner whose self worth is defined by their job title.

Lol

We’re not judging you because you want a promotion. We’re judging you because you selfishly make a ton of work for everyone else so you can feel better about your pointless life.

no reason in the real world. no reason that matters / makes you fulfilled / makes you feel proud to be doing your job

success in this industry is proportional to your ability to not notice or not believe that your work is pointless
