Some people are like you and simply view a job as an economic transaction, and some people think that since they are spending a large portion of their day with a particular group of people there is little downside to making friends and socializing. I will tell you a little secret though, when push comes to shove I will cut 'economic transaction' employees in a heartbeat without a second thought but I have sometimes gone out of my way to give a 'work friend' a break or spend a portion of my week finding them an internal transfer. I feel no enmity towards those who are a bit more mercenary than I, but I also do not have even the slightest bit of loyalty to people who make their attitudes in this regard clear (i.e. learn to fake it now and then and you might do better...)
