is greed contagious

really is it? is it arrogant to judge another human to be arrogant? like the stock traders and their management who seem to maniputlate the market to their political whims? greed. i want more this is not enough. this is not to my liking. more . more. more .. really . to be grateful is the deepest level of spiritualty and i heard that's how to get to the next level. but, isn't that greedy to want to get to the next level and not like this.
