I agree. I think that the definition of "greed" may be an issue here. If people defined greed the way I do, surely they wouldn't support "greedy" activity.
To me "greed" is when the desire to acquire money or property or control exceeds ones ability to use good moral judgement.
I sell signs. Of course I want to make all the money I can selling signs as long as doing so is moral and legal. From time to time I have someone to ask for a product that is clearly not the best product for their need. I am the sign professional, not them, so I council and guide then into making a decision that is rational and will give the the most sign for the least amount of money. A few weeks ago someone from a local college called me wanting 100 "cut vinyl yard signs", I could immediately tell that they were spending the colleges money and didn't really care that cut vinyl signs cost $30 each, they were just placing an order as they were told to do. I asked a few questions and determined that there was no need for "cut vinyl" and that a product that would fill there need for just $4 each would be 100 screen printed signs since all the signs were identical (cut vinyl is for very small quantities). I probably could have screen printed the signs and charged them $3,000, and they probably would have paid, since they didn't know any better. Instead, I recommended the screen printed signs for $400, and they agreed that made better sense. I did what I felt was the moral thing to do, even though some people would probably suggest that a more profitable sales technique would have been to have taken the order for 100 $30 signs.
When these Wall Street fellows were making morgages that they new were very risky, and then bundling them into CDO's, and paying rating companies to give the CDO's a top rating, they by God KNEW that they were selling a crap product for a top price under misleading circumstances. Or when they call their clients and try to push a particular stock on them, just because management has told them that they would be given a bonus for selling shares of that particular stock, that is fixing to go under, thats greed. The investors is not an expert, the salesperson is presenting himself as an expert, has a certain responsibility to only sell products that they think will provide good results to the customer. When they make their recommendations based not upon a good value to the customer, but based soley upon making more money for themselves, thats "greed". It is most certainly a sin, and while it may not be illegal, it is certainly immoral.
What is not "greed" is the desire to make as much money as one can, while acting with good moral judgement. So if I have a product that costs me very little, but is of good quality and utility, and as long as I represent the product to be exactly what it is, and as long as I am not putting the customer into duress with sales tricks or high pressure tactics or threats or any of that nonsense, then I am not greedy when I try to sell as many units as I can, regardless of the fact that I am making a big profit from each unit.
The desire for riches is not the root of all evil, but greed is the root of a lot of evil.
