During my time as a medic in the Army, my work environment was definitely one of impersonal egoists, myself included. No one was out to be cutthroat or sabotage others, but competition was extreme to be recognized as the best at their job. We had a common agreement that every person must look out for themselves as no one else would be more invested in your own self interests than you would be. This may sound like a place that could be hostile, but we had great comradery and a close brotherhood. But like I said, in terms of professional development and success, no one came before self. I would even say it made us better medics, as the desire to be the best pushed us as individuals to seek the latest training and education.
For me, this is a great example of how egoism isn’t necessarily an evil or morally wrong mindset to abide by. Of course we cared about the well-being of the medics in our section and the people we were medically responsible for, that went without compromise. The difference was that we simply had to look out for ourselves at the end of the day, and though it may be difficult for some to understand as many people are stuck in the “team” mentality, you’ve got to realize this method worked for us. We were competitive, and we were better for it.
