You are either misunderstanding or operating under false assumptions.
a) Misunderstanding: I’m not suggesting that people get rewarded that have done less. That conclusion does not follow from: don’t engage in reward system that disproportionately benefits your ingroup. I see how you would arrive at that conclusion, but it is false. Not engaging in policies that disproportionately reward your in-group does not necessitate rewarding an out-group by a different metric. These are not two sides of the same coin.
b) False assumptions: Staying longer at a company does not equate having done more. It is entirely possible (and even quite common) that a new hire will contribute a lot more then established workers. A new hire brings with them a new perspective. They might not contribute directly, but they might be asking the right questions which gives more senior workers a better perspective etc.
