[Rambunctious]

From a company's perspective, just because one person gets a market rate that is higher than the rest of the team, the entire team can't simply be given a raise. While this sort of largesse may work for Google & FB, I doubt it would for those companies that grow in single digit to low teen % per annum.

Also, if the person given this raise is not amongst your top performers and now ends up out earning the rest of team, it ends up affecting overall team morale. Your star performers then start to feel short changed and think they have to leave to get a raise.
