I don't think you have seen the point of many of my comments, whether literally or implied- greed is the cause of many problems and even though you're Atheist, you may have seen/heard "Money is the root of evil", from the Bible but the whole saying is "Love of money is the root of evil" and that's true now, as it was over 2000 years ago.
While it's true that greed has resulted in many innovations, it also creates class systems.
