Isn’t the answer obvious?: Work has become much more precarious again and looking like you aren’t into it is a competitive disadvantage that few can risk.
Or maybe some people actually do love the work they do... Are people really this disenfranchised that they can't possibly imagine that some people really are doing work they enjoy? I love my career and the work I do is fulfilling and gives me a sense of accomplishment
Do you think most people love their work the way you do?
