That so called "old saying" you mention makes no sense in the real world. From my experience top % engineers hate working with bottom % engineers since they massively drag things down for everyone, so firing the bottom % ones actually makes life better for the top % and convinces them to stay, and vice versa, keeping bottom % engineers around for long actually convinces top % engineers to leave since they want to work with equally competent people who can get shit done and not be around incompetent people who coast and watch the clock, or worse, drag everyone down.
