~10 years ago, when I got my first job, I was in the minority, pretty much the only person cynical about big companies' claims how "people are our most important resource", how important is the company "culture" and all of that corporate kumbaya. And, at that point, the vast majority of people around me cared and wanted to do a good job, going up and beyond.
Fast forward to now, and pretty much everyone has the attitude of "f**k these guys", doesn't want to be there and will do the bare minimum to get by. And that's exactly what companies have demonstrated that they deserve.
People are tired of job hopping to get market pay, dealing with bulls**t, and being thrown under the bus at the slightest hint of an economic downturn.
