I feel like this is a biased and unfair question. Do I feel the 1% are greedy? Yes. Do I feel the 99% are greedy as well? Yes. While there are some rockstar human beings who do not have greed as part of their persona, I feel like greed is an innate human trait. It's part of being human.
Are the 1% greedy? Sure. Just like everyone else. Human beings are greedy by nature.
Are the 1% more greedy than the average human? Well, no, I don't think so. We're all just human. Most of the 1% simply had more opportunities than others. The difference between that businessman who makes 500K a year and that witty garbage man who makes 50K a year was, mostly, opportunity with a little bit of "good" choices thrown in.
