Earlier quoted context omitted.
The reality is that not everyone brings equal value to an org. Some are rockstars and others are meh. It’s natural, and you should be incentivized to improve.
This is a bs argument. If there is actually a "rockstar" and a "meh", they should be at different levels with clear payscale.
For large companies, that distinguish between "role" and "level", sure. But a LOT of companies aren't big enough to do that.
