What does "generation shift" mean Fujito?

If 1 leaves and isn't replaced it's changed.

Show me the proof that someone is leaving and not being replaced. It's a running theme in your posts that you make claims without backing them up.

All you have is your opinion that people don't retire from a job you're they're happy with, which is a load of baloney. Even if we were to accept that axiom, people in different countries and even different places have different attitudes about when you retire, why, and general attitude towards work. The emperor of Japan himself stepped down for health reasons- who wouldn't want to be an emperor? People retire for many reasons, and "I'm not happy with my job" isn't usually one of them.
