I personally felt like it was a reference to the complete lack of corporate loyalty to it’s employees.
It’s hard to have a “career” in the classical sense the way my 90 year old grandparents did.
You can still choose a field of work and if you’re lucky you’ll get to stay in it for most of your adult life, but between outsourcing in IT, fields being made redundant as technology advances/changes (from cashiers and retail to journalism and marketing, accounting, and phone work) and whole fields of manufacturing work getting shipped overseas, the number of lifelong fields of work available is rapidly shrinking, facing fierce competition for jobs, and becoming a moving playing field faster than most people can retrain for.
“HR” jobs could get halved or more with chatbots providing benefits and payroll adjustment information. “Big data” is doing most of the “market research” that advertisers handled manually 30 years ago.
Big money is still trying to sell us the “career” dream because it leads to the school loan debt they feed off of and temporarily gluts fields with workers to reduce salaries, but only a few handfuls of fields of work really have “career” style options anymore.
I took it not as an insult to the people trying to have one, but as disdain and disgust at how the word gets bandied about like so much bait on a hook when the reality is fastly becoming far different for the 20- and 30- somethings of today.
That might be just me being both charitable and jaded, though.
