Well imagine having the entire first like decade of your career happen before the Reagan era blessed the relentless pursuit of profit at the expense of anyone, even if they were core parts of your company? Before Private equity, rampant off-shoring, etc. etc. etc. Even in the nineties people were saying things like “don’t switch jobs too often because it will make you look disloyal.” Well now, in many industries, if you have the same job for 5 years people think you’re just unmotivated. Considering how little employers are willing to invest in employees compared to recruiting shiny new ones, it makes sense.
