Yes, and this is something that is routinely overlooked. Work identities run deep, and they are not easily changed.
Andrew Yang actually made a strong point when he was talking about automation-driven job losses way back in 2019. He said you can offer the best and most expensive retraining programs imaginable to help people displaced from their jobs move to fields like healthcare - but most truck drivers, even if out of work, will never even consider retaining to work as a nurse. Identities are not as malleable to the whims of supply and demand as some might want to believe.
Truck driver to nurse is special kind of issue, because nursing is feminine coded occupation and trucking attracts men who want to prove own masculinity. But they will take jobs that are not that much feminine.
And nursing also require a lot more study then people assume, 40 years old trucker will have hard time spending that much time in school even if it was his lifelong dream.
