Exposing employment for what it is.
The whole point of corporate capitalism is to do exactly that. The corporation is a machine whose most-optimized purpose is to turn people into money.
Human dignity is not a concern for it.
If the people fired had years of experience in the job and the new people hired don't, the company lose talent. Is bleeding money in an endless loop of training people just to let them go soon after that, has trained somebody to nurture their competitors, and some of this people could even make new companies out of spite and compete with their former boss.
I guess the saddest thing, is that everyone just accepts this.
Fortunately, I had the means to retire, and I did.
I think it's about to happen again, but a lot faster, this time.
