Any citation about this claim? Because in my experience, it's completely incorrect.
Outside of the US, lifetime employment is a heavily coveted goal, because economies outside of the US are in a terrible shape overall with unemployment rate routinely above 10%.
Inside the US, except for white collar workers in major cities, long time employment remains the holy grail of most of the workforce, even though the US economy is in a pretty good shape overall.
Interestingly, even though Dan Lyons technically belongs to the white collar community that is probably not interested in lifetime employment, it's pretty obvious to me that when he joined that semi-startup, his goal was a lot more to write a book about it than embracing the party line and planning a long career there.
I mean... you're hiring Fake Steve Jobs and when he's out of the company, your executives try to illegally get a copy of the book with the futile hope that it won't get published... Seriously? What did you expect?
