Also, it's like the exact definition of greed...
An excessive desire for more, well above and beyond what you need, which is already beyond what you have? When $2 billion in profits just doesn't quench your thirst. No, you can do better. Even if it requires taking from those who do need.
You can use your own statement against you however. "An excessive desire for more, well above and beyond what you need," there are people who live quite well on less than 50k a year. In fact 50k puts you right at the mean national household income. It's all relative.
