Agreed. Honestly reason #1 far and away that I decided not to put all my eggs in that one basket.
The other day I watched a JustPlanes "flight in the cockpit" series inside the last 707 to be retired from the US back in 1999 shortly beforehand. It starts off on the walk around with a crusty old pilot who starts out by introducing himself with, "I've been in this flying business for a long time. Started out with Pan Am...and then off to Eastern...and then...it was off to the non scheduled carriers...and now..." and you could just see the pain in his eyes as he didn't even finish the sentence standing outside the Challenge Air Cargo plane with 3 stripes on his shoulders just before retirement. It was honestly depressing. If Google went down tomorrow, I doubt the majority of skilled workers would have trouble filling positions at other tech companies who would love to have them on board. But with the way this industry works, a seasoned 747 captain who was just laid off is likely going to find themselves competing with their coworkers to start over in the right seat on one of the lower paying frames at another major, or perhaps even back to a "commuter" as a street captain or into the right seat for the rest of their career.
Some like
@DPApilot have the right combination of great networking and great timing and very quickly pay their dues and move onto good jobs in their early 20s, some like the guy above get absolutely chewed up and spit right out in the dirt when they hit a bump in the road(or two, or three) and none of the connections or experience in the world can replace their wages in an acceptable period of time. Good thing high QOL jobs seem to have plenty of time off, at least that gives everyone a fighting chance to have a side(or primary even) income.
