I've worked for enough crappy managers that I know how much that affects my job satisfaction and work-life balance. I'm at a point where I'd probably (and, currently do) sacrifice 10-15% of my salary just to work for someone who is respectful and interested in my development and wellbeing. I'd bet others are like me, and if you truly mentor and develop someone, you won't need to pay Netflix-level salaries to retain them.
