> Hardly an Amazon-only thing. In fact, enterprises need this mindset, because people moves on, retires, or just suddenly die.

Enterprises typically have this mindset. Most corporations I worked for in fact treated employees exactly like this.

But ultimately I fully agree with the whole of your post. I just had to nitpick about this.
