I think the audience here tends to be capitalist/libertarian/objectivist. This means that for many, your assumptions about what is moral/"on shaky ground"/etc. are seen as somewhat baseless and irrelevant.
Maybe a better topic to discuss would be the ongoing debate over the proposed Harvard MBA 'oath' (http://www.alumni.hbs.edu/bulletin/blog/2010-02-19.html). Actually, I think a quote in that article answers your question quite succinctly:
He concludes: “Rather than focusing on pledges, businesses should make sure that managers comply with their fiduciary and ethical responsibility to maximize the wealth of the people who pay their salaries, i.e., the shareholders.”
Lastly, it's not common to have these kind of open-ended discussion topics.
Too bad though discussions like this aren't more common here, Ironically though, by not having a discussion like this invites more government interference into the internet. Kind of like the finance industry.
