sauron, you seem to be confusing the people who actually create the game with the businessmen in charge of the business.
I'd doubt there's much of a difference there. I'd guess the lines are quite blurred.
I'd also doubt anyone there could get a job at a hedge fund or Goldman.
And I'm using a very, very broad interpretation of "greedy." I'm using it as "trying to make more than necessary to get by." Which is the way many people here often seem to when accusing companies of being greedy.
