> I tend to agree here. There must be top performers in pool B willing to invest time and effort to move to pool A given how lucrative it is. One thing to remember is that pay might be bi or multi-modal but that doesn't mean the work is actually likewise shared out by "performance". There are lots of reasons other than merit why people might end up in a lower or higher paying position. You'll also find people going up or down between these positions over their careers. A normal one from my experience is people taking big paycuts to work in Europe.
