Agreed. When I left my old job, even a 20% raise would have been significantly smaller than I moved onto. In order to even match it, it would have to have been about double that. As it is, even just a raise won't change things much, as there are almost always other reasons someone wants to leave too - it could be that the work was unfulfilling, there was no room to grow, the company had no direction, management was clueless, the internal politics were toxic, insufficient recognition for work, etc. Those issues don't go away with a raise, that just convinces people to tolerate them for a while longer.
