I’m not sure where my copy of the book is, but “bump” right back at you.

The “I made this” factor is in my experience the primary driver, properly “justified” to management who also wants ownership.

I’m unsure what a fix looks like, given the preoccupation of HR departments hiring process with “young” and “innovative” - that HR speak for “cheap”, vs. “experienced” and “considered” - HR speak for you’re too old and expensive, but mostly too old.
