Salary Scales and the Moral Fiber of a Culture

I think there is a direct link between economic equity (not equality) in a society and its moral well-being.
       Earlier this week the Wall Street Journal had an article about CEO pay in 2010, specifically the compensation of CEOs in the oil and gas industry. The article stated, "CEOs of oil and gas companies had the highest median value of total direct compensation at $13.7 million in 2010, up 17.3% from the year before."

       The highest paid Oil exec is R.W. Tillington of Exxon-Mobil. His total direct compensation for 2010 was more than $21 million.
       It seems to me that political liberals tend to be on the side of condemning this type of inequity in our culture, while conservatives tend to say little about it, or they applaud it as the way capitalism works.
       Liberals see this as some kind of moral or ethical issue while many conservatives do not. What is most puzzling to me is that Christians often have little to say about the matter, with the exception of quoting a few biblical passages which seem to say that acquiring wealth is a good thing (there are many more passages in Scripture which warn of the dangers of great wealth).
       I am concerned about what this kind of inequity does to a culture, and why Christians seem to be unable or unwilling to find a voice in society to advocate for a simpler lifestyle. Should it not be the Christians in a culture why\o work for equity and a breaking down of socio-economic groupings (classes)?
