Who's doing the transforming?

I recently got back from Ireland and have a few quick anecdotes from that trip I'd like to share to illustrate this conundrum of how we as Christians fit into the business world:

• First, as a continuation of last week's question about Philip Morris, I saw several (all?) cartons of cigarettes in Ireland with a huge warning in big black letters (probably took up 25% of the front of the packaging) saying simply: "SMOKING KILLS."
• Second, on the flight to Dublin, we boarded the flight (2 hours delayed) and then were delayed another hour and a half due to a "problem with the generator." Many of the passengers on the flight were connecting in Chicago to London. After the generator delay, a flight attendant announced that all of the London passengers would miss their connection and they had been rebooked on a flight for Saturday (this was Thursday). When one passenger asked whether American Airlines would reimburse him for having to stay in Chicago for two nights, the flight attendant said, "No, I'm sorry, we don't reimburse for weather delays." That just straight hacked me off. We were clearly delayed by the malfunctioning generator and American Airlines' policy is to compensate for inconveniences caused by mechanical problems. The problem was, I used to travel for a living so I knew the policy -- the passenger asking the question clearly was flying for the first time so he was going to get screwed.
• Third, at the Avis desk, the agent asked the customer in line in front of me whether he wanted the "gas option." This essentially means "Do you want to pay for a full tank of gas now?" In other words, it's a total rip off disguised as convenience ("You can just return the car...don't worry about filling it up") -- the only way you even break even is if you return the car completely empty (and often their price per gallon is higher than average). Again, I knew this because of my job but I'm sure many unsuspecting tourists buy into the "convenience" pitch and throw away money. And companies like Avis are happy to take that money.

So my question is this: what happens to people when they become employees that they cease being human beings and morph into revenue-generating/cost-cutting robots with no love for their brothers and sisters?

This is probably a better way to ask the question I was attempting to ask last week. I realize that my previous question (and others before that) pointed more toward action than heart, suggesting that a line can be drawn between "good" and "bad" actions. Even if a line can be drawn (the law) that is not the message of Jesus. Let's talk about motivation, about a heart that is being sanctified to become more like Jesus. How can we reconcile the call to conform to the character of Jesus with motivation of companies like the ones highlighted above?

This is not theoretical -- if you're like me, you face this conflict every day.
