Yet, companies just love to hire instead of retain. Take an employee who just got trained/experience and is now worth $N, who is currently making $N-2. Most companies I've worked with would piss and moan about giving that employee a raise to $N-1. They'd rather let him leave. Then, they suddenly have no problem hiring a relatively unknown employee and paying him $N+2. It's never made sense to me in all my decades in this business. Obviously value-destroying behavior that's routinely done by most companies.
