Having a bad boss has always been a top reason people leave a job. In academia it can be fatal because the boss has so much power and leaving for another job isnt always an option in a specialized field or a field where one institution is the leader, and moving would mean a huge step down in an early career.

And it's mostly not about America's recent-years drama over research funding:

I've heard little about academic research careers in Europe - but even decades ago there were major problems in the US with extremely long work hours, meager & uncertain pay, and very poor prospects of achieving either good pay or tenure. Given those - would a good supervisor tell young researchers to stay in academia?
