I'm not as concerned about a potential "sacrifice of morals" as I am about the risk that "power corrupts."

Being put into a position of power over people's lives (jobs) tends to give that person an inflated sense of their own worth and deflated sense of the other person's worth. Being desensitized to criticizing someone's performance as part of your job, getting into the habit of censoring one's own comments for political repercussions, being forced to assume a person's value based on their salary or influence: these are all signs of the corruption that is possible. Dabbling in the corporate world isn't the same as selling your soul.
