Appears this issue is getting to be a "thing" here. I ran across the following article and thought it worthy of being kicked around. Perhaps those retired pilots sufficiently motivated to undertake this would've done it by now anyway ?:
"Why don’t we call on industry to promote hiring of experienced, retiring airline captains into the flight instructor ranks?
In addition to increasing pay to make this attractive, such a plan needs a high-limits instructor liability policy to cover the captains. One of the biggest disincentives for these folks to teach what they’ve learned in a lifetime of flying is that they usually have significant personal assets they put at risk if they instruct."
