Part of the problem is that loyalty is so over. Back in my dad's day, you wanted to amass a retirement portfolio, or get more vacation time, or other benefits of being with a firm for decades. Now, those seem old-fashioned, and there are fewer pension plans and more contract workers. Hypergrowth is what matters. Getting challenged, learning stuff. Layoffs can happen at a moment's notice, making more of a "what's in it for me" attitude.
